Mouse cursor size becomes big mysteriously in Windows 7 - Radeon 5700 and 5750

Those of you who got your shiny new Radeon 5700 or 5750 or any of the 5XXX series video cards must have already noticed how the mouse cursor size increases automatically and mysteriously to about twice the size. I have confirmed this finding even with the latest version of the catalyst drivers (as of 22 Nov 2009).

This issue is so easy to reproduce. If you have Windows 7 and any of the Radeon 5XXX cards with the latest catalyst drivers, you cannot miss it!

My system is a Windows 7 x64 Ultimate box with the Diamond Radeon 5750 with 1 GB RAM. I also have the latest DirectX distribution files installed (from dxwebsetup.exe).

So far the only way to decrease the cursor size back to normal in Windows is to restart the machine. If you have other solutions, do share them with us!
