I upgraded from Win98 to Win2000. Camera is now 'stuttering' mouse actions

[oso]

Not sure if this is the correct forum / will cross post in Vision.
In VC++ (6.0).
I upgraded an application from Windows 98 to Windows 2000 (disk crash) with a Silicon Imaging 3170 (acquire only) camera file. NI-1428 board.
Everything is fine, except, when I open the camera for acquisition, the mouse 'stutters'. If I close the camera, regular operation returns.
Is there a setting or driver that would account for this? Difference in the timer functions?
In MAX, this behavior doesn't exist (should eliminate the camera file)
Any suggestions / more questions?
Thanks in Advance,
Chuck Bear

I don't know about the driver settings, but there is one OS setting you might want to check. Windows 2000 has a foreground application priority boost that sometimes can cause problems with driver performance.

To turn off priority boosting, right click on "My Computer" and choose "Properties". Select the "Advanced" tab, click the "Performance Options..." button, then choose "Background Services" under Application Response.
