Alessio,

I have NOT read the whole thread BUT your statement of 'on one PC only' makes me suggest that you might want to look at the Display setting for "Small Fonts" / "Large Fonts" on THAT PC.

You find this in: rt-click anywhere on Desktop, click Properties, click Advanced and then look at the selection in place. It may be set to Large Fonts" and that can cause different display from "Small Fonts".

Sadly, even in WinXP (Home) a display still shows differently depending on this setting.

good luck
