Yes, Image is declared as public in my class:
TImage Image;

80 and 60. I've checked them with the Debugger just a moment before

Yes, I tested it on 2 different machines and the results were the same.

I don't know exactly, I tested the code in windows with Qt 4.4.0,
4.4.3 and 4.5b and it work perfectly.
