I wonder...
I tried changing my system to Large fonts..to see how it would react..And it didn't touch my desktop at all..It changed fonts elsewhere..In all windows..and elsewhere..--but didn't touch my desktop..not the names or icons..
I only changed my font size under the Appearance TAB..I didn't touch my DPI...I kept it at Normal as well..
I kept my resolution at 1024*768.. 32 bit..and simply changed my fonts..
I would think it should react the same way..When he changes his fonts back to large..All goes back to normal..
When i play a game..made in the resolution 1024*768...My desktop changes briefly..then i play the game.
When i exit out..my DT goes back to normal..
I would think that if he simply changes Fonts under Appearance TAB and has 1024*768 rez...It would react the same way it does for me..
Then when he exits out...change it to large again..
Not sure why its touching his desktop..
I think its his resolution that's doing that...and he may also have Icons set to large icons as well maybe.....?
Anyhow..just wanted to mention that..Not sure if that will help or not..
