A VI that worked flawlessly for years while loaded in a subPanel suddenly has ActiveX controls diappear or go blank and other native LabVIEW controls fail to update properly.

Whats the Cause?

Reason Was:

==========

LabVIEW VI was Corrupted. How? Hard to tell.

Fix:

===
-- Copy block diagram via SELECT ALL

-- Open new VI

-- Paste

--- Clean up whatever needs to be cleaned-up

Voila. FIXED!!!
