Hi Jeff,
thank you for pointing me to vizconfig.
It seems that I can put that to good use, though I'll have to rework my menu system...
My opinion is to prohibit unwanted user input rather than telling the user afterwards that I didn't like his input - meaning, I'd prefer that you can't enter letters or non-number special characters into a number (int, float) textbox at all.
what about that TickerDialog and Panels, though...?
Best Regards, Walter
