>What is _VFP.AutoYield property set to? Can you show your code?

Nadya,

That's it! :)

I had forgotten that we needed to set AutoYield to false for this form because we have a 3rd party treeview control on there. Interesting, though, that DOEVENTS didn't help. Well I will just experiment with wait states using INKEY to see what's the smallest amount I can get away with.

Thanks.

Laterness,
Jon
