imrrk[/quote]Hi imrrk,
Where do you call readSettings()? It is commented out at the constructor.

Do you really expect being taken serious when crying like a childish kiddie? Come on, get serious!
-And look at your code if it is ever able to do what you expect it to do!-
-Or better: Use a debugger, set breakpoints and step through the code. You will find the error yourself then within seconds.-
-Hopefully nobody will tell you the solution here, as it has no learning effect.-
EDIT: wrong read of code, sorry
