Canon ZoomBrowser

I've just installed Canon ZoomBrowser on my PC and whenever I have my
wireless broadband connection up it hangs the machine. If I switch
wireless off it seems to run ok. Anyone seen this behaviour before &
know how to overcome it.

Initially I installed 5.x from the supplied CD but I've just
downloaded & installed latest ver off Canon's website. Still have same
problem.

Thx

Nigel
