Program crashed when explorer.exe gets restarted.

[korolek13]

I'm still experimenting with my workspace and sometimes I need to restart Windows Explorer to make some changes. But when I do that, the program crashes and I have to manually reopen it every time. It would be awesome if issue is solved, thanks.

Hmm, it doesn't seem to crash for me when restarting explorer. I only noticed that for some reasons the Tray icon disappeared when I restarted explorer, but the program was still running in the background.

It's possible that some window HWNDs are cached in the program (for optimization purposes and to prevent too frequent calls to the same FindWindow functions), and then some functions use the invalid window handle. However, it seems like I already update them for the mouse clicks:
