every once in a while IDEA opens the New Project Dialog
instead of reopening the last project - for no obvious
Also I sometimes notice that clicking on File->Reopen->XYZ
has no effect. (YES I DO HIT IT CORRECTLY ;)
At repetitive chosing of the menu entry it then always works.
Not critical, just details... seems like this IDE develops
a little life of its own, with some tics and quirks ;)
