I used to run a program called Task Arrange in XP which allowed me to re-arrange the buttons in the windows taskbar. Currently it does not work with Vista (crashes explorer.exe) and therefore I would like to know if anyone knows of a similar program.

The site for Task Arrange is Elias Fotinis TaskArrange :: Arrange the Windows taskbar buttons

I tried using the contact info on the site but was unsuccessful.

Taskbar Button Manager Taskbar Button Manager - arrange the Windows XP taskbar buttons any way you want using drag and drop, for free also allows the arranging of the buttons on the task bar. It does not support Vista as yet but they said eventually, the program will support Vista.

Try Taskbar Shuffle, it is completely free and the author says it works in Vista:

home of the nerd cave | taskbar shuffle and more

I was in the same boat as the original poster. This program works on my Vista (pre SP1, haven't made that jump yet). So far, so good.
