Why is this thread marked "resolved"? I see no resolution at all, and I'm having the same issue on my MacBook Pro with iCamSource v1.4. The last version worked fine, but once I upgraded it stopped working.
When I double-click the app, nothing at all happens. When I try to delete the app, I get a warning that tells me it can't be thrown away because it's open, but the app isn't visible as a running app in the launch bar (but it DOES show up as a running process from the Terminal).
I've tried restarting my Mac, then throwing the iCamSource app in the trash and re-installing it, but the same thing happens when I try to launch it.
You should actually solve issues before assigning them a "resolved" tag, for people like me who search the forums before posting.
