Losing doubleclick in windows XP

[hnm123]

Hi,

When i exit BS player, i lose my
middle button assignment ( double click )
on the desktop and in the windows explorer,
but not in the internet explorer or outlook express
and if i restart BS player double click
still works fine, but still nothing
on the desktop and windows explorer

Sometimes i can regain the assignment
by reconfiguring the mouse settings again.
but i lose them again when i use BS player

I am using v1.0 build 810.
Mouse is Logitech MX 500
with the latest drivers
on Windows XP Professional
with all updates ( except SP2 )

Does anyone have any idea as
to why this happens
