I just found out what causes my ICAD4 to shut down:
With ESNAP turned on, I type NONE to switch it off and click any point. If I use Toolbars or F3 to switch ESNAP off, ICAD works perfectly.

Anyone else has this problem, or am I alone with this?

You're not alone. Does the same thing to me. Also, using the local menu (shift+right click) to turn off snaps will shut down the program.
