trouble with thunderbird
 

when thunderbird is open and i try to open mozilla browser, it does't open. loads, but no window. when mozilla is open, thunderbird opens fine and they both work fine on their own. it's just that mozilla refuses to start when thunderbird is already working. what's wrong?
thunderbird 0.8
mozilla 1.6

Are you clicking on links in Thunderbird and its not opening or what? What happens if you have Thunderbird open and you try to run Mozilla from a terminal to see its output (if any)?

yes i am trying to use the link in the main menu of suse9.1
for some reason running it from the terminal works fine. but i can't see what the problem is. the link runs the same command (mozilla %).
