Thanks for all the help.

Putting the icon in WBstartup and making it a project did the trick. I also added the tooltype "DONOTWAIT". And not the PolyGlot starts fine. It dosn't autologin but thath is a minor problem. Wetter also starts fine but I have to update mannually.

Is the login and update problems something I can fix with tooltypes?

To be honest I do not know what the "DONOTWAIT" tooltype does?
