weird subtle bug in xp pro

[sobriquet]

Hello.
Since a while there is a subtle issue that has been bothering me. I'm
sure I didn't have this problem before, so something must have been
installed on my system that is causing this problem.
When I'm working in any particular windows application, occasionally,
windows will spontaneously switch to a different application, which is
very annoying.
For instance, I might be editing an email or a posting and suddenly,
for no apparent reason, it switches from Internet Explorer to winamp
or another program and I inadvertently press keys that activate
functions in winamp, thinking I'm still working in Internet Explorer.
It happens regardless of the application I'm working with and I
suspect it switches to winamp because I usually have it running in the
background (playing music) and I tend to start it right before
starting Internet Explorer or other applications.

Does anyone know how to figure out what's causing this problem and how
to resolve this issue?

Kind regards and thanks in advance for any help, Niek
