Go into
System Preferences, click on
Accounts, choose your account on the left, and then click
Login Items on the right. Remove the list item CROSS OVER CD HELPER (or similar) by single clicking it and then clicking the
- just below the list. This will stop that program from running when you start up your computer

. If you now restart, it
should all be back to normal.
If that doesn't work, try just changing the displayed items on your desktop to 'refresh' the settings.
Click on the desktop, go
View at the top, and just try fiddling around with the icon size. If nothing appears then, then close that little window and press
Command +
, (comma). This will bring up the preferences window for Finder. Click
General at the top, and then try un-ticking some of the boxes, and re-ticking them.
Hope one of the above works
