Actually, this is the source of my unease with this code as well.
Therefore, I plan to drop that closeQtapp call from
plD_tidy_extqt not only to make the code cleaner but also because the
current code would fail if some external qt application tried to use
the combination of extqt with, say, pngqt (e.g., to make a permanent
PNG file corresponding to what was displayed on the screen using
extqt).

So unless you have some second thoughts about removal of the
closeQtapp call, I plan to push that change later today after
your current appCounter fix is pushed.
