As the title suggest, for the last little while I've been having issues with the "Move applications to current monitor" setting in DisplayFusion. Some of the issues might be app specific, so I'm not sure if it's something that DisplayFusion can improve or not but I figured I'd give it a shot here. Some of the issues are:

1) Start menu on occasion, launches correctly when I press either Win Key or the icon, but when I start typing it keeps relocating back to the default monitor regardless on which monitor I'm working on.
2) When opening a new instance of Firefox it often relocates itself to the monitor where the other instance is open in regardless of where I'm currently working.
3) Certain dialogue menus or pop-ups don't get relocated. While I understand these aren't technically "new applications" it would be nice to have an option to allow relocation of ALL new windows to the current monitor (if possible). Some examples include the color picker dialogue window in PhotoShop, or new connection notices in MalwareBytes Windows Firewall Control.

Sounds good, I created the trigger to resolve the issues with new windows not relocating. Also while I'm at it, there is another separate issue that I've noticed. When I have a full screen video playing regardless of the player, I notice that every few minutes the taskbar will briefly show over the video then hide again. Is this an issue with the taskbar being re-drawn or something else?

Yes I have it enabled because without it, I was experiencing other issues. If I remember correctly, when the option wasn't selected and I tried using windows key to gain access to the taskbar when a full screen application was running (Game/movie) I couldn't until the application was closed.

For which issue, the taskbar not appearing? If so, that happened many years ago and I've had the "reload taskbar" feature turned on ever since so I may not be able to replicate it but I will try.

There is another post on this recently where I show a screenshot of a setting that I think affects/controls this behavior.

Sorry for taking long to respond, the issues described happen randomly and it's hard to pin point the exact time but I managed to record the logs for both issues. I've attached the two logs.

- The one labeled with "_NoTaskbar" has an instance where the "Allow taskbar reloading while full screen application are running" has been disabled. During which a full screen application (In this case a full screen game) was running and I pressed the windows key, and no taskbar appeared. Just the start menu. Incident occurred on July 22nd, 9:18.38 AM

- Second incident labeled with _"TaskbarOnTop" occured WITH the "Allow taskbar reloading" option enabled. Movie was playing and randomly throughout the movie playing the taskbar would display for a second or so before disappearing again (with no input from user). Incident occurred at 7:20.24 PM. There was also another incident of this issue in the same log file around 6:56.13 PM-ish but I wasn't able to capture the exact second it occured so probably 6:56.10 PM +/- 5 seconds

Not that I've noticed, granted MPV is my primary video player for videos and is the only one that I use fullscreen for extended periods of time. I just tried with Media Player Classic and haven't seen the taskbar pop up yet, but that's not to say it won't since the behavior is random.

I haven't touched any of those settings, so it's set to the default of "left". This is the same issue that's been described in this other thread https://www.displayfusion.com/Discussions/View/taskbar-reloading-when-fullscreened/?ID=c9fff3eb-2442-47b2-a5a9-1c5a415dbe50 so I'm not sure if there is any similarities here that might be able to help identify the issue?

I suppose I wouldn't mind a work around of basically disabling the taskbar on the specific monitor where a fullscreeen application exists, and re-enabling it if the windows key is pressed or if the user exits the fullscreen mode? But I'm not well-versed enough in programming to right the script for such a thing.

That's fair. Two additional pieces of information that may help in the search for the cause. These things may only apply to me, but maybe not others:

1) This issue doesn't happen with "active" full screen applications (ie: Games) it only happens with passive ones like video players.

2) This issue has existed for several years, but since it has been just a minor annoyance I never took the time to make a thread about it until now. So it's not a new issue that came about with the most recent version of DisplayFusion.

For now I'll use the custom functions! Thank you.

So far I've tried to replicate the issue (as much as I can anyways, since it's random) with the "SetWindowPos: Log Calls" setting turned on as requested, but I have been unable to do it.

I'll try again during the weekend and I'll let you know if I'm successful.

After watching a 3 hour movie I didn't see the taskbar pop up even once like before. I'm not sure what changed, I tried reverting the settings back to the way it was before and still nothing. I'll continue testing and upload a log file if it happens again.
