lag on blue highlighter when selecting folders

This is not for everyone but I have noticed when I select lots of folders and you get a blue highlighter it can start to slow down. To fix this:

1. right click my compter
2. then advanced
3. then performance settings
4. untick show translucent rectangle
5. then re-tick show translucent rectangle
6. then apply

Now when you highlight your folders in Windows XP there should be no more lag.
