problems with screen rotation
With some help from these forums,portrait mode was successfully implemented, I then reverted to landscape OK,When I tried to return to portrait the next day I recieved the following message.
"you cannot rotate display while a game or 3D application is running,close all games and 3D aplications etc etc"
I have never used a game or 3D application,cant see anything suspicious running,Any thoughts.
Monitor LGIPS236 running native resolution of 1920x1080 32 bit colour on Nvidia8600gt card on windows XP proff.
Any clues would be welcome,it seems strange that it worked one day and then not the next,cant think of anything that I did that could have caused this.
