Well...I can see that you did NOT search at all on this issue as this has been addressed before.
It is a known bug right now, the only way around it is to:
A. Switch to a screen that doesn't have an iList on it before leaving the comp.
B. Add a CMD to the "ONSUSPEND" command in the exectbl.ini file to always go to a screen that doesn't have an iList on it..ie "ONSUSPEND","MAIN"
