I'm on windows 8 and installed classic shell 3.6.4.
Updated to 3.6.5, I get random crashes of explorer a few times a day.
Could not figure out what causes the problem.
Now back to 3.6.4, it still crashes, but less frequent then 3.6.5.
Is is when you perform certain actions, like open the start menu, or run a program, or do a search?
I'm using my browser, and wanted to switch to another application / access my desktop,
I hit the hot key alt+tab or win+d, then I realize explorer hang up, and after a moment, it restarts itself.
Send an email to firstname.lastname@example.org. I will send you instructions how to make a crash dump and send it to me.
