MouseMove and MouseClick performance issue

[tele]

Dear All,

I have written a simple script to control the operational of a flash programme. Basically, my script move the mouse cursor to a specific coordinate and do a left click there. As I need to run the programme in different type of computer, I found that the speed of mouse cursor movement is extremely slow in a compaq PC with Nvidia Vanta LT (16M video RAM). The cursor speed was normal when on a PC with other type video card.

I wonder if anyone of you have encountered a similar issue. If yes, should I replace the Nvidia Vanta LT card with another one please?

Thanks!

Terry
