strange errors

After installing CIS 4, some of my programs giving me strange errors that i didnt see them before, i am using windows 7 64bit final
sometimes comodo tells me that it added some application to sandbox, but when i see the sandbox program box, its empy ! and the program wont start and if start it gives random errors
whats the problem ?

Sandbox now seems to look less than perfect, I believe COMODO will continue to improve it.
good luck
