Ok, here's what happened.
I had FryingPan crash that required rebooting the whole system. After reboot, the screen resolution was down to 800x600 from the one I set at 1280x1024 (24-bit). The Preferences only show in Mode List the resolution and colour depth that I have set previously i.e. 1280x1024, 24-bit. The Use button is disabled regardless of what I select. If I click on Save button, the screen will get jumbled up and requires reboot.
What's even more troubling is that I can't close any windows because when I take pointer to window title bar, it changes to pointer for moving window, including when I hover over any controls in the title bar i.e. close window, move to background/foreground, etc.
I have tried to add new screen modes but regardless of what I do, it always boots into this low resolution mode which I cannot change.
UPDATE: After some some time (I haven't done anything) the window controls got back to normal. I rebooted and I'm now back into screen mode that I have used previously. I don't know what happened but everything is back to normal.
