YSFlight window not showing up

[Bmontour26]

So I was clearing up my temp file space on my computer, then I opened my YSFlight window (d3d9) and it was invisible. but it was there. I then proceeded to redownload and extract, with the same result. Then I tried different versions but those didn't work either. Thanks in advance.

I had those errors in YS2018 whenever I send a shortcut to desktop. I don't know why.

In your "Documents/YSFLIGHT.COM/YSFLIGHT/config" folder, delete prevwindowsize.cfg

I had the same problem with the 2018 version running on Windows 10 pro. YS started minimized and whatever I did, it would not maximize. Also when I hovered the mouse over the icon on the taskbar, the thumbnail just showed a white screen. I'm not sure if it was a windows problem or a YSflight problem, but pressing Win+Shift+M fixed it, and I've not had the problem since.
