Vlad,
I'll certainly try getting rid of them myself, that won't help the issue of VFP page faulting even after only editing the form they are on. I've trying setting all possible combinations of _vfp.AutoYield = .f. and sys(2333,0) and nothing helps the page fault on exit after editting.
>Just a guess: try releasing explicitly these objects. I found out that a COM object is not always released (ie its memory is not released and its destructor not called) when the variable that references it goes out of scope in VFP. In the mean time a oMyCOMObject = .f. solves the problem and the COM object is released for real.
