Thanks for the response Sergey - I'll be reading the wiki article next. And yes we do have SP1 installed.
BTW do you think timers could have anything to do with this??

>>Hi there:
>>
>>We have a vfp7 application based on the mere mortal framework. In the main progam file there is this code in the last line right before it exits:
>> RELEASE ALL EXTENDED
>> CLEAR ALL
>>
>>Every once in a while it gives a C5 error both when running the program from within vfp, and the actual executable. We havent been able to isolate or pinpoint any particular scenario where it can be consistently reporduced.

>>Also in the previous version of the application which is based on the same code minus a few enhancements, we never get this error.

>>Any help, suggestions will be appreciated.
