Wordpad and high CPU usage

When Wordpad is run on this system I've noticed that CPU usage hits 47% and
uses ~5.2m of memory even when idling and with no document loaded. OTOH, my
notebook and several other computers show 0% and 4.7m under the same
conditions. The notebook has similar specs, with a P4 630 (3.0 ghz) and 2gb
RAM. The OS is XP SP2 with all updates. I do not get the same issues when
Notepad or Word 9.0 are run. These run as expected, with no CPU usage when
idling.

Needless to say, something is awry here, although I have no such problems
with any other app and the system is very stable. Having Wordpad running at
any time heats the CPU up 15C or more than normal and has other obvious
side effects on performance. Any help with this bizarre quirk would be
appreciated.
