- You know, I've noticed something similar to this, which is very strange.
- I've never seen any actual flicker on the monitor, but I have noticed that
- the apparent load on the CPU changes as you move the pointer over
- different icons or windows (and there's no particular reason for the
- applications to suddenly receive extra wimp events when this happens -
- certainly not for icon bar icons, anyway). You can see this if you're
- running something like !Usage; you can see the CPU load change. You can
- also sort-of hear it in the CPU noise which breaks through to the audio
- system. Often wondered what's going on here...
-
- While on the subject of CPU monitors, does anyone use Ran Mokady's RISC OS
- 3 CPU monitor? Sometimes when it is running and open, the window manager
- seems to decide to do a complete screen update, for no apparent reason.
- Strangely this only happens when there are a few filer windows also open;
- if you close these, the strange behaviour stops.
-
- I don't suppose there's any later and more optimised version of this
- program around now? It's a nice gadget, but you don't want to use it too
- much of the time - a usage monitor which itself consumes 20%-odd of the
- CPU (on an ARM3) is a bit much!
