big t...if you mean switching from one user to another then...i ended up using this little utility (thanks Doug for the referal) and it has worked a treat
- simple setup.exe fil
- run the utility while logged in as each user (I have 5 users on my XP box
- then each user sets their own resolutio
- when you 'fast switch' from user to another - they all keep their own resolutio
- wife is happy :-
