I'd like to start by saying that I'm relatively new to DisplayFusion but have been extremely impressed. I converted from UltraMon a few months ago when the 1/2 price sale was going on. I was hesitant because UltraMon was doing its job but I'm glad made the change. DF seems to be a little better about staying out of my way and I love the re-organize feature of the secondary task bar. The only area that UM beats DF is the setup of mutli-screen wallpapers. DF does a decent job of this but UM was much easier and I felt like I had more control in that area.

Now, onto the bug I found...

Starting with v3.1.8 I am randomly getting titlebar buttons "stuck" in the middle of my primary desktop. I have not been able to determine which window is causing the problem but I am trying to narrow it down. I believe it is related to a window that flashes on the primary desktop and then hides itself. When this happens the associated titlebar buttons are not cleaned up. The only way I've been able to get rid of the buttons is to close DF and re-open it. I'm attaching a screenshot of the buttons. If you need me to run some logs please let me know.

Thanks again for creating such a great app and supporting it so well!!

And clicking these buttons didn't reveal the related window?
