Thanks Nadya! It works now. I tried the Lockscreen and that solved the final problem of the form not refreshing or repainting properly. Here's the code in the GotFocus for the form that works now. Thanks again.

THISFORM.Lockscreen = .T.
* Find Attempts record that goes with Tube record
CREATE CURSOR atts;
(Ext C(3), Seqno N(2), Placed C(18), Route C(10), Ext_Reas C(12))

ATTS_CNT=0
SELECT attempts
SCAN FOR attempts.mast_id = tube.mast_id
	SELECT atts
	APPEND BLANK
	REPLACE atts.ext 		WITH attempts.ext
	REPLACE atts.seqno 		WITH attempts.seqno
	REPLACE atts.placed 	WITH attempts.placed
	REPLACE atts.route 		WITH attempts.route
	REPLACE atts.ext_reas 	WITH attempts.ext_reas

    ATTS_CNT=ATTS_CNT+1
	SELECT attempts
ENDSCAN

THISFORM.lstTube_tries.Requery
THISFORM.lstTube_tries.Refresh
THISFORM.Lockscreen = .F.
SELECT tube

Picky, picky, picky that's VFP for ya! At least of still have some hair left. I was starting to pull it out. There is an extra flash when the form appears, but I think I know why. Otherwise, it works perfectly now.
