I'm testing a long running vfp program and found these problems

Wait window messages freeze (in different parts during different runs)
Added debugout message, but it also freezes.
I set escape on, but program doesn't respond to ESC
Added saving message to disk which shows that program continues to run
Finally process finishes correctly

It's almost like it locks screen and keyboard out.

I have windows 7 64 bit and VFP sp2. Any idea what may be the problem?

TIA,

Alex
