Windows that should be hidden aren't...anymore.

Strange problem. Not sure exactly when it started happening; probably a
hotfix.

When I log into XP, I get a small window caption floating around on my
desktop. Exactly which window it is varies with every login, but every
indication thus far shows that these should be invisible windows--only they
have the WS_VISIBLE style.

As I'm typing this, the window caption is "MCI command handling window".
The owning process, according to Spy++, is explorer.exe (makes sense). I've
also seen the caption "ccApp", which is a process spawned by Norton
Anti-Virus, as well as an entirely blank caption. That's all these windows
are--a caption bar, no resize/min/max button, and without any client area.
This is mere speculation, but these look like perfectly innocuous windows
created by processes that use the traditional "invisible window" method to
receive system event notifications from Windows. No biggie, I've written
this sort of application myself. Only, as mentioned, they lack the
WS_VISIBLE style. These windows are necessary for things to work properly,
so I have to keep them on the screen...but they do get annoying, especially
since they also add an extra entry on the task list.

Has anyone ever seen these, and if so, is there a known fix?
 
Have you done a System File Check via

SFC /SCANNOW
