Error message: Title: Start Plesk PopPass Service Message: Error 997 at Start service POPPASSD: Overlapped I/O operation is in progress. Options: Abort|Retry|Ignore This is the first message received when starting Plesk 7.5 beta for windows. Because of this or any further messages the tray icon is white and Plesk doesn't work. I have Simple DNS Plus, Merak Mail Server & Serv-U FTP Server installed. Maybe a clash with Merak? Control panel still disabled when Plesk PopPass Service disabled from Plesk services moniter. Please help in full ASAP. I'm pleased with the progress to Plesk and believe it to be the best control panel but errors like this aren't acceptable.
