rule matched, but not executing on 4.01 (worked on previous)

Hi all...
i have various rules on hazel and all were working on 3.8, but now only 1 does not work consistently on 4.01
this part always works:
i have a folder - Process_iFlicks (which sits inside my download folder)
when new video comes in - iFlicks is opened by hazel applescript
iFlicks - processes video file and deletes it after it is complete
this part worked all the time on previous release
when Process_iFlicks is empty (or equals 0 files) - then it closes iFlicks (using hazel applescript)
now on 4.01
i can see that the rule matched... but the rule does not get processed and it does not close iFlicks
however, if i run the rule manually, then it will close iFlicks.
Has something changed in 4.01 that is preventing the rule to execute? do i need to reset some timer?
