Bisoncam - USB 2.0 - "graph cannot preview"

Ive googled for this one to no avail, apparently its a vista linked issue, so
hopefully someone can help.

I have an inbuilt Bisoncap 2.0 USB webcam on my laptop. When i open the
console or msn messenger, half the time it loads fine, half the time it gives
an error message saying "this graph cannot preview" and the screen is just a
blank white (msn cant find it at all). If i restart the computer it works
immediately, but this as you can imagine is a pain. How do i prevent or cure
this?

Thanks.

Although it is not an answer to your basic question, can you avoid the
restart by simply logging off and back on?

Nope, Apologies for such a long delay, the only thing ive found which works
is a complete restart, which as you can imagine is rather annoying.

I have the same problem till I found the absolutely working driver in
my Axioo notebook at

Find the driver with *.exe, and all you have to do is double click the
file...
Enjoy your Bisoncam... :)

Keep up the fine work, moron. The post you replied to this time was
