Since the last cooker update, whenever I click on a url in Thunderbird,
if firefox 2/3 is already active another instance of firefox is started
rather than the existing instance being reused. Also when this new
instance starts two tabs are launched both containing the web page for
the url. What do I look at to determine what is causing this issue? This
is occuring in kde3 under 32 bit cooker.

Steve
