This happens in RubyMine 3.0 (RM 97-125, Nov. 29): When I first fired up the debugger it said a gem was missing and asked if I wanted to install it. I replied 'yes' and it took awhile (because it had to build native extensions), but after a few minutes it was done.
Now when I fire up the debugger I get all of the right windows, it says "Connected"... and then after a few seconds switches to "Disconnected" - without even firing up my home page. I don't have any breakpoints (or anything else) set, nor have I changed any of the default settings.
I am using your IDE on two machines: a 64-bit desktop and 32-bit laptop. Both are running Linux 10.10. This problem occurs on the 64-bit desktop; the 32-bit laptop fires up the home page in the browser and then sits there waiting for action (displaying "Connected") like it's supposed to.
I did a search of the forums but didn't find any reference to a problem like this.
Anybody have any ideas?
