Remote assistance screen resolution doesn’t match

Hello

How to use Windows XP remote assistance when host PC is running on a screen resolution 1280×720? (A LCD 50″ screen)Or any other resolution which doesn’t match my PC screen resolution.

The problem is that mouse cursor location doesn’t match on my PC.

I guess there is a solution as remote access doesn’t have this problem when remote host is running at 768×1024 and my remote client PC at 1024×1280?

Thanks
