Grigore,

>In the code I had a call to a standard messagebox ("The report was saved to (path)". When I removed the call, my problem was gone. I have absolutely no idea why.

>If i put it back, the problem reappears. I moved all the code in a separate method, call it, then messagebox, then thisform.release. And now it works ok - the oExcel object is release quite instantaneous (the file wasn't big - about 30 rows in one single worksheet).

MessageBox() is modal your form can't release while any of it's methods are on the call stack.

>However, while I was digging the problem I found another problem and this is definately a bug in VFP8 SP1:

>well... this is not a big deal - no one uses the prgs in this way, but I thought it worth a mention.

I don't see this, If I click the ! button it runs and focus returns to the command window, so the ! button doesn't reenable, until I click focus back to the code window.
