Hi Jack,
Some things you might want to check:
Are all apps closed when you're trying to adjust the height?
Have you changed the screen resolution property?
Have you restarted the PC to see if that clears it?
Check to see if 'High Contrast' is in play in the Windows control panel Accessibility Display settings.
What size are the icons set for if you right click on the desktop and choose appearance (Windows XP?) Sometimes a setting there for
Icons or Icon spacing can 'grow the taskba, or if you have an additional Toolbar in the same line as the TaskBar (right click
taskbar=>Toolbars)
========================
Nope, that won't do it either...it's a real mystery to me. cause it's
unlocked but can't be made smaller...only bigger. >>
