Geoff,

In addition to Josh's recommendation to put a DoEvents in the loop. I'd suggest you get rid of that high processor use loop entirely.

Just us a polling timer that checks every couple of seconds to see if the process is done. It may want to issue a DoEvents but it probably wouldn't be necessary.

WAIT, INKEY() and DOEVENTS() all basically allow the VFP event loop a chance to process events.

>thisform.label1.caption = "Something else"
