Windows 7 Not staying on top?

[Tripledrop]

I installed win 7 recently, and have used both gadgets and rocketdock. I have set all 3 of my gadgets, and rocketdock to stay on top.

However, they don't always stay on top. After a restart, and every-so-often, other stuff takes over (eg firefox).

If I click on them, they then stay on top until the next time it goes wrong.

Is there a way to make them stay on top?

Nope It only happens every-so-often...

Graphics is up-to-date, and I'm pretty sure everything else is
