Anyway both will occasionally have a very short display "blink". Under
"normal" conditions, other than wondering why, there seem to be no other
indications or symptoms.
"Old" Solitare was transferred to both machines from XP.
Other that the problem I'm about to describe, no other difficulties seem
to exist.
If the "blip" occurs while dragging & dropping a card the card may be
duplicated! One is on the original card pile, and the other on the new
location/pile. An undo will restore to just one card in the orginal
location! Or, you can continue to play with two identical cards!
Both systems do have AVG active. Anybody else noticed this sort of behavior?
???
