Minor computer question

This is a guess but you could check your Accessibility options under Control Panel.

Make sure your settings aren't enabled for those who are impaired.

It could also be the bit depth that your graphics card is set to.

You may or may not want to reboot to see if that brings up a warning window or something on reload.

I have no clue what kind of freaky shortcuts that crafty Mr. Gates has created.

I pushed random keys on my keyboard once and all of a sudden it burned when I urinated....for like a week.

I would just try anything that is graphics-related on your system.

what happens when you reboot?

I hate to be the one who notifies you, but your dog wrote this earlier in your blog:

And your color quality/bit depth is 16 or higher? See if there is a control panel for your video card, too. There could be a hotkey sequence that your dog activated.

I know ATI has something called a Catalyst Control Panel that has all sorts of neato settings.

If that doesn't work, you can try clicking on the "Troubleshoot" button on the SETTINGS tab inside Display Properties. The last option "I cannot set the video resolution above 640 × 480 with 16 colors." may help.

What do you mean when you say your "window is huge?" The whole desktop - icons, font, task bar, etc are now gigantic? Is your screen resolution too large? Is it just the font on your desktop?

Have you double-checked your screen resolution? Right-click on your desktop, select "Properties," click on the "Settings" tab and verify that your resolution is at least 1024x768 or larger.

On the same tab, click on "Advanced." Make sure your bit depth is normal (96 dpi) in the Display box.

If it's just your font, click on the "Appearance" tab and make sure the font size at the bottom is set to "Normal."

Depending on your graphics card or chipset, there can be many hidden short cuts floating around. For example, Intel graphics accelerators enjoy hiding a keyboard shortcut that rotates your screen 90 degrees. My dad's cat has done that to him a couple of times, and the girls down at my apartment complex's office have done it several times. Whenever it comes up I disable the ability to rotate their screen.

Nuke it from orbit. It's the only way to be sure.

Slide the resolution slider over to the right (In Settings-->Control Panel--->Display)

You're welcome. I seem to remember answering this exact same thing once before, but I think it was due to a cat and not a dog. There seems to be some little known keyboard combination that lowers the resolution, which is vulnerable to pet paws.
