I have the steam version of DisplayFusion and using since the last time it was on sale on steam. At that time i had windows 8.1 on my pc and everything worked well. The best feature for me is to lock a fullscreen game on my primary monitor so that i can use a browser or anything else on my secondary monitor. This worked well with Blizzard games, WoT and other games from Steam.

My problem started the moment i upgraded to windows 10. I am using a Logitech G400 mouse with its gaming software and game specific profiles in it. The problem i faced, that i lock a fill screen game on my primary monitor, then i alt + tab out to click and use things on my secondary monitor, maybe a browser. After i return to the full screen game lock on my primary monitor, the logitech software uses my default profile instead of my game profile. It seems to me that there is a litle miscommunication between the softwares or somekind of event problems. The main thing i think that the problem is on the DisplayFusion side, that when i not use the lock feature everything works fine. At alt + tab the full screen game goes down to the taskbar, the logitech profile switches to the default one, and when i re entered the game from the taskbar the logitech profile changes to the current game profile that i attached to it. (this issue was not present when i used windows 8.1 with earlier version of DisplayFusion, a changed to windows 10 not much after the upgrade possibility came alive)

I tried to search, if it is only with me or it is a known bug, but i couldn't find anything.
If i missed something i am sorry.

Thank you for your help!

I am sorry to hear that, i hoped that this problem isn't that big. Is it becouse of the new windows and the way it handles things?
Is there any settings or things i can do on my side that maybe solve this?
