Ah, I see, so there was a subtle change to it - and when I hold my cursor over it, a tooltip says 'Taming 1 process'.  Now maybe I was using the wrong word: when I run this on my other machine, a tooltip pops up periodically without me needing to move the cursor, but that doesn't happen here unless I intervene as you suggested. 

I am running XP SP2 on a 2.66gHz Pentium 4.

Hi, new user here - I really like ProcessTamer, but it's not speaking to me much.  I think it's working, but although I have the box for tooltips ticked, it hasn't given me any yet, even when running your test app.  How can I tell if it's working?  And though I expect tooltips will become boring pretty soon, so I'm glad I can turn them off, I would like to see 'em for a few days first.  Any suggestions?
