I imagine yes, 'cause this is the whole button:
if self.convertThread.State = self.convertThread.Running then
app.showErrDialog "A batch is already running: you must abort it
or wait until it finishes before starting another conversion."
else
if self.niceCheckBox.Value then
self.convertThread.Priority = self.convertThread.LowestPriority
else
self.convertThread.Priority = self.convertThread.NormalPriority
end if
self.convertThread.Run
end if
return
so unless the self.convertThread.Priority = ... stmnts take 20 sec I
don't see what else would "beach-ball" my app (with a "ImageTrak not
responding" warning in the Force Quit window list to boot, really
fooling the user into thinking the app crashed and tempting him to
force-quit: not pretty).
Is this the beauty of a thread?
