>>My forms, which used to release just fine in VFP6 no longer do so. I can't tell where it's happening at this stage. It's as if there's a new unreleased object bound to the form that I don't know about (but my base class code is unchanged).
>>I you click on the forms close box the close button becomes disabled, whereas in VFP6 the release/queryunload etc would fire and shutdown the form.

Ok, I've now narrowed this thing down. I've put the code in a separate post under this category called "Example of a form..." Message # 566754
If I don't get someone telling me I'm nuts, I'll post it to the MS bug reports.
