PrinterSetup() => Dialog won't open

[gkuhnert]

Hi,

after my pc is running for a while the printer setup dialog won't open any more (I call "printersetup()"). I don't get any error message.
Maybe this is an approach: if I call MsgInfo(comdlgxerr()) I get a Value "10". Has anyone a clue what this might indicate? Or how it can happen, that the printer setup dialog won't open?

(If I restart my whole computer, this problem won't occur. It also won't occur if I make a small test-program only calling printersetup() )
