I think this is usually related to RAM (hence resources). It may also be
the video driver.

Can you reproduce in more than one machine?

Maybe reboot, copy form, load copy and delete items or code on copy and/or
put a few sleep commands in between and test to see if you can pinpoint the
problem.

I would also look for recursive code or code firong multiple times when not
needed.
