click one destop icon another one opens .. why???

When my XP pro SP2 system on an ASUS m6b00n laptop comes out of hibernation,
the desktop icons do not work properly. When an icon on the desktop is
clicked the nearest icon at the bottom of the screen is opened instead. If
the icon is single clicked to highlight it, the improper icon is the one that
lights up instead. It makes no difference what kind of icon it
is..program,folder,etc..The icons in the taskbar at the bottom work properly
and programs launch properly from the startup menu. If you check the
"properties" of the icon the "target" information is correct.
Generally if IE7 is run and the internet is used for awhile, upon closing
IE7 the desktop icons function properly. If the system is restarted instead
of hibernating everything works Ok. The computer has run for years with no
trouble..this just started up..... ideas??
