Can't Keep Kompozer from taking Over.

Hello. I've got a laptop I'm running OpenSuSe 11.3 with KDE4 on. In addition, I've installed the KDE3 version of KDEPIM on it. But not the KDE3 desktop.

My problem is that if I have both Firefox and Kompozer (a website editor) installed, every time I click on a web link in an email, it starts up Kompozer INSTEAD of Firefox.

I can't find any way to prioritize Firefox, except to uninstall Kompozer. Can anyone tell me where to look to make clicking on a url go to Firefox and not Kompozer. The KDEPIM is from 3.5.10.

Thanks
