Vista - Wandering Gadgets and fickle Desktop Icons.

Wondering if anybody else has this problem.

Wandering Gadgets.

I download and install a gadget, add it to sidebar, bring up the
sidebar to desktop, un-dock the gadget to the desktop, and close the
sidebar, leaving the gadget as a desktop item. I place this gadget in
the upper left corner of desktop.

Screen-saver kicks in when the computer is idle, just like it's
supposed to.

I come back to the computer, give the mouse a shake to disable the
screen-saver, and my gadgets have moved to the left about 2 inches.
They are all in the same position horizontally, just not vertically.

Tried enabling both Auto Arrange and Align to Grid, (right-click
desktop, View, check Align to Grid and Auto Arrange), but neither
keeps the dern things in place?

Fickle Icons.

Secondly, after either restart, or the above mentioned
screen-saver/return to computer scenario, some of my desktop icons
have reverted back to the default white folder with the blue E icon. I
have to right click these, and re-assign the icons.

Any suggestions?
