Memory leak

[GRAY, PAUL]

We are running IE 5.5 under Windows 2000 using CybraryN as a front end.

Our librarians are complaining about 'constantly' having to reboot stations
to clear memory errors ---
"The instruction at ox70feae36 reference memory at oxo2fao28b. The memory
could not be read."

MY best guess has been that this being caused by repeatedly opening and
closing Internet Explorer  
90% of the choices on our menu are web sites which means every time a user
makes a new menu choice they launch IE.
The stations are also heavily used for chatting and game playing (despite a
'stated' ban on the latter).

Assuming my diagnosis is correct -- I know of no real solution -- except to
reboot the stations periodically to flush memory.

Is anyone else seeing this error message repeatedly?
If so - what have you done to eliminate it or reduce its frequency??

HELP!!!
