Just asking. Since its a customer, are you charging them for advice you use from this forum?
You would install all the latest drivers for motherboard, USB, video, that Microsoft doesn't install and check that DMA is enabled.
All spyware and parasites would be removed as well.
Best of luck,
Running Win2k, all the latest fixes on a 'frankenstein' with Pentium 2.6gHz processor, lotsa disk and 512 Mb memory and a MS optical mouse, I have a customer with a really strange mouse activity problem. It seems that if any program pops up a window that requires a mouse click, the window closes if that window is outside the boundries of the original program window. Sometimes, it is even the same area as the original. I have talked w/ Intuit (Quicken 2004) about the problem and they say it is a setting in the machine, not a problem with their program. I have looked all through the registry and the docs I have with no reference to this mouse activity. It is not the property that causes the mouse to jump to the 'default' in a message box. Has anyone seen this before?? I have been chasing this for about 2 months now and have no idea where to look next.
