Hi, I upgraded from a relatively old version (2.5. or 2.6. something) to 2.7.1 early in December. Graphics card is a Matrox P650 DualHead AGP.
About two weeks later or so I started to get a mysterious screen behavior. There's no clue that Ultramon is responsible for this, but it's the only candidate I have at the moment.
The behavior is that after the machine has run for one or two days all newly painted windows get "scrambled", it looks like all the pixels get moved a bit to the right or left and even a bit up and down, so the screen is barely readable and all lines are "shaky".
That starts with one window and then happens with every window that gets the focus (by clicking on it). Finally, both screens are completely scrambled. The only things that are not affected by this are the three button icons on the small Windows shut down dialog (what you get when clicking Start Menu/Shutdown).
The first few times this happened I rebooted the machine. Now I found out that simply changing something in the display dialog initializes the display driver in such a way that it goes away.
I didn't install new drivers (for any hardware) last month and probably not any other software that is running all the time and that I would imagine could be connected to this.
So, this might either be a hardware problem, a problem with the video driver or any other software that is hooked in the display process.
Since I can correct this without a reboot I don't think it's hardware-related. And since I didn't install new drivers I'd rule out drivers as well. I had reenabled Matrox Powerdesk after installing 2.7.1. I had disabled it because of some other interference between UltraMon and it earlier. So, I disabled it again, but this doesn't solve the problem.
So, I now "hope" that UltraMon may have something to do with this. Were there any reports about such a behavior or does this ring a bell?
For diagnostics: can I kill UtraMon.exe and UltraMonTaskbar.exe in the running system without a problem?
Thanks, Kai

My guess would be that this isn't related to UltraMon, sounds more like a display driver issue.
Terminating both UltraMon processes shouldn't cause much problems, but I would recommend shutting down UltraMon via the UltraMon icon in the system tray, this way all resources will get released properly.
If shutting down UltraMon doesn't fix the problem, try if uninstalling UltraMon makes any difference. Drivers used by UltraMon's mirroring feature will still be loaded even if UltraMon is no longer running.
