For some reason, several programs on my machine (XP Pro, SP 2) are not able to call up the default browser (FF 1.5). The main problem apps are the Stardock apps I use (DX, Right-Click, OD+). I've also noticed the problem with MyBase and it sometimes comes up when trying to register newly installed software. Sometimes simply nothing happens (with Stardock products), or a message comes up saying that the application could not be found (or some other variant). There are no other problems with any of my apps. Other apps, MS Office in particular, seem to have no such problem. Has anyone ran into this? It's a pain in the butt, but not big enough to go through surgery through. Any ideas?
