SRS -

Your graphics card toolbox program (even if it's just a motherboard "integrated graphics" thing) may have an adjustment for "Hardware Acceleration." You may also find the same thing in Control Panel - Display, depending on what the PnP setup decided your graphics hardware is. Often at Display on the Settings tab, the Advanced button will offer to open the "real graphics card" setup; but this varies with the hardware you have. A few machines may not have an accessible adjustment for this, but it's fairly common on recent ones I've seen.

Most of the time the acceleration can be set to "maximum" but sometimes it does something similar to what you describe if set too high for the hardware.

Some flat panel monitors also get testy if you try to set at anything other than their preferred resolution. Newer ones are more flexible, but some older laptops, and I would presume some similar era desktop FP monitors, show you lots of different resolutions but then curse at you and change it back if you try to select one other than what they want. Sometimes they'll let you set an "off" resolution, but then they misbehave to make you sorry you did that, and you have to apologize to them to get them to work right again.

A worn/dirty scroll wheel on a mouse can do some similar things, but you'd likely make that connection pretty easily if you use it for scrolling.
