How to temporarily fix mouse cursor suddenly becoming extra large

Posted by robkraft on July 23, 2012

I am running Windows 7 and I have two monitors and occasionally the mouse cursor on one monitor turns into an extra large size.  While still functional, I find it annoying.  Apparently this caused by a flaw in some video drivers from ATI.  My PC is using ATI Radeon HD 4550 drivers on ViewSonic VA2226w-11 Monitors.
To resolve this problem, I run the magnifier tool built into Windows 7.  Just starting that, and leaving it running, causes the enlarged mouse cursor to go away.  A reboot will also usually fix the problem.  To run magnifier, simply type magnifier in the search box off the start menu.
