Hi SysTech Guy. This is a classic symptom of a default XP video driver being installed instead of the one provided by the video chip or video card manufacturer.
The first thing to try is to roll back the driver to the previous version. SP2 may have replaced it. The old one may be the proper one.
Control Panel > System > Hardware tab > Device Manager button
Click the plus sign to the left of the entry Display adapters.
You should now see an entry listing your adapter model. On my PC there are actually 2 entries with exactly the same description - I have no idea why, so don't be alarmed if you see more than 1 entry.
For each entry listed right-click on the entry and select Properties.
On the pop-up window select the Driver tab.
Click the button Roll Back Driver. Answer "No" to the question about the Troubleshooter. Click OK.
Close all the windows and restart your PC.
When fully restarted retest the motion smoothness of the windows.
The driver rollback may not fix the problem. In this case you need to reinstall the proper driver. If your PC came with a Drivers CD then run it and install the driver for the particular chip or card listed previously in the Device Manager.
If you don't have a Drivers disc then you will have to go get the driver from either the PC manufacturer or the video card manufacturer. All laptops and some desktops have video chips built-in to the motherboard, that is, they don't have a separate video card. All other desktops have a plug-in video card.
To figure out which video adapter you have: What is the make and model numberof your PC ?
