Why doesn’t Vista let me rearrange my taskbar

One of the features I like from – ahem – Ubuntu, is that it lets me shift the tabs of the task bar around. I just like to put my work on the left side and my nonsense on the right.

Windows Vista places it based on chronological order, left to right. And upon the restart of explorer.exe due to reasons I never fully understood, it auto arranges in an order not sensible to me at all.


Why why why!
