Don't forget that in Windows, there is always a process "explorer.exe", that is hidden, and represent the taskbat and systray.
So, I think that when this explorer crash, TWizard cannot verify and use icons in systray, then crash.
I don't think is it easy to fin a solution, because if you set differents rules for explorer.exe and TWizard, the rule for explorer will be applied when you open "my computer" for exemple ... not really what you want!
However, I have detected a bug with the autoreload function, I think I will publish a minor version to fix it soon ... may be it could help ... (or not)
