IE 8 zoom issue

Has anyone ever come across this problem and if so, what did you do to correct the problem.

Windows XP, MS Updates up-to-date, IE 8.

Problem: While in IE 8 the view will zoom level will increase to 1000%. If you bring the view level back to 100% it will increase back to 1000%. I rebooted the computer to see if it would reset, however when I go back into IE 8 it will zoom back to 1000%. Any suggestions to correct this problem is greatly appreciated!

Thanks in advance.
