>I have a form that was originally created in VFP3, the system has now (or is in the process) of being upgraded to VFP6. There is one particular form in this system that, sometimes when I say 'modi form formname', sometimes when I right click and say run form, and sometimes exiting the form when running it, it just locks up the computer. Can't even ctrl-alt-del to get out. I have to turn it off and start over.
>This is the only form it seems to happen on, and it appears to be inconsistent in where it happens. Has anyone seen this???

Not exactly helpful, but:
I have an app created mostly in 3, then moved to 5 (where it runs fine), but it has serious problems in 6 (runs extremely slowly, some objects don't function correctly). I think two major upgrades is too many for it. I'm eventually going to recreate the objects from scratch, copying most of the code, and I figure that should clear things up...
