I would have suggested using evnt_multi with a timer interval of zero,
I've never had trouble doing this.

No.

I posted a solution to this problem about three weeks ago, call wind_set
with  WF_NEWDESK  and a object tree address of 0, this restores the

I've never tried this, but it should work: do a evnt_multi call and
wait for the cursor to leave a small box (1x1 pixels) around the current
mouse postion, if you get a msg that the mouse has moved show the cursor.
