I take it that you're talking about your task bar and windows (control panel etc) and that you're using Windows XP.
If so here goes:
Task Bar: Right click on the task bar and left click on properties. Make sure 'auto-hide' is unticked and 'always on top' is ticked. Then click on 'apply' and then 'ok'.
Windows: Right click on 'My Computer' and then left click on 'Properties'. Click on the 'Advanced' tab at the top and then click on the 'Performance options' button. Click on '.......For best appearance' (where ..... are words I cant remember coz I'm on a PC with a different OS at the mo!) and then click on 'apply' and then 'ok'.
That should do the trick.
If you're talking about something totally different, then sorry
