mmhh ok thanks Redwing. I did a test and see now i can't make a minimal settings file with my basic layout. I created a clean musicbeesetting.ini with <TabsInCaption>true</TabsInCaption> but MB says the settings file is corrupted
By the way, here goes a remind of a wish i posted when i was a child
Adding the option to the SHIFTED startup menu, the one which appears when you press shift key while clicking the icon to run MB, to run it with the default settings temporally for making this bug hunting process easier.
