From the Known Issues section in the help file:

There are a few possible problems you might run into:

The "taskbar buttons grouping" option in Windows XP makes it impossible
to separate the grouped buttons and sometimes interferes with the
movement of plain, non-grouped buttons. So, it is recommended that you
turn this option off (right-click on the taskbar, select Properties and
uncheck "Group similar taskbar buttons") if you use TaskArrange.

This also does what it says :-) in that if you've got the option to
group similar taskbar buttons selected, then it won't work. Pity, but
that's how it behaves on my WinXP Pro system.
