I'll try one more time. In the meantime I looked at How to pass cursor between two VFP datasessions (without using XML) FAQ #29297 and it's a bit too complex. Perhaps cursortoxml would be easier in my case.

UPDATE. Yes, moving the setfocus at the top of the method seems to work. Now I'll try to hide the button again.
