Fred,

If I have a long running process in the Click of a button I do this:

this.Enabled = .f.
* do a whole bunch of stuff
this.Enabled = .t.

Which seems to help, the user generally doesn't go clicking disabled items. You can also use = inkey( 0.01, "HM" ) to suck up mouse clicks, but may have other side effects on the cursor if you have controls like textboxes on the form.

Now, if you go placing DoEvents in there you may allow the user to kick off another long running process from another button while the first is still running.

>>>No, I have not tried your test. The "processing" I was referring to was SQLs to build a cursor for a report and running the report. When I used to return from the report, if the user had pressed the button while this was going on, the report would run again. DOEVENTS stopped that for me.
