First off, thanks for such a great tool!
Ctrl+F > enter a search term > Match Whole Word Only > Wrap Around > Enter >
word is found > Esc (to close search dialog) > F3 > Application locks up and need to end it and restart.
This does not happen all the time, but often.
Sometimes it also happens keeping the dialog open and using the
'Find Next' button. When it does, I see that the 'Find What' dropdown is empty (maybe a clue).
Prior versions had similar lockups, but not nearly as often.
When a search is finished and dialog is closed, focus is to another open application and not MyGeneration.
I know how difficult it is to track down erratic problems, so if I find anything more definitive, I will post back.
