I'm unable to reproduce this on any version of Emacs I currently have 
installed (21.3, 22.3 or 22.0.92). The earlier report was using 20.7, so 
I would expect to see the bug in at least 21.3 if it was consistently 
reproducible.

Is there any other software running on your system that might affect 
keyboard handling in subtle ways?

In my case, this appears in view-lossage as:

l o w e r c a s e <return> U P P E R C A S E

I am using a ThinkPad X60 and whenever I press caps lock a small window
pops up at the bottom right of the screen to tell me so.

Emacs displays the desired behavior when I run Windows in Safe Mode, and
whatever is displaying the caps lock notification window is off.

Still, Emacs is the only program that seems to have trouble with this.

Can you find out what is the application that displays this small window?

While trying to figure this problem out (which I have experienced for 
months), I seem to have fixed it. Don't know exactly what I did, but the 
most likely suspect is this:

1. Start ThinkPad Keyboard Customizer Utility
2. Options...
3. Check Disable Keyboard Customizer
4. OK
5. Close
6. Start ThinkPad Keyboard Customizer Utility
7. Options...
8. Uncheck Disable Keyboard Customizer
9. OK
10. Close

I am asking what is causing the pop-up for future reference here:

Since the problem now seems to be fixed, it seems you can mark this bug 
invalid. Sorry about the inconvenience.

I think it is better to leave it open, tagged as moreinfo, until we 
understand the cause, so we can document it in etc/PROBLEMS.

Thanks to the observation of Black Qin on the help-gnu-emacs list that 
this is triggered by scroll lock being on, I have tracked this down to 
an inapproptiate default value of w32-scroll-lock-modifier. Putting the 
following in your init file should fix the problem if you cannot update 
immediately:

(setq w32-scroll-lock-modifier nil)
