I am running a legacy program in XP Mode (Adobe Pagemaker 7.0). When I need to save a document, usually to a Windows 7 drive, it takes a very long time to do so - unless I move the mouse pointer within the window. I know this sounds strange but I've confirmed this behavior many times.
I'm guessing that moving the mouse generates an IRQ which temporarily gives the XP mode process higher priority. If it is a large file which takes longer to save, I can observe the save process speed way up when moving the mouse and slow way down when I stop.
Is there some setting somewhere to speed up the process without the mouse movement - my hand is getting tired.
