[bold]climbhigh[/bold] - You weren't running under a limited user account by any chance ? I ask because I've had some problems when not running under an Admin account on XP Home SP2. For example, If I place a DVD in the drive, PowerDVD 6 starts up and loads the DVD menu. At this stage switching between full-screen mode and windowed mode is as quick as normal. However, if I play the DVD in full-screen mode for about 10 minutes, then when I switch to windowed mode the redraw of the Desktop is really slow with a lot of disk access. This slow redraw only occurs when running under a Limited User account. Anyone know what's going on or have a suggestions on how to speed it up when running under Limited User Account ?
