Applications Open Multiple instances
I have a clean install, about a week old, of 12.04 that's until now run fine.
I installed a second monitor today and in the process of stumbling through nvidia something odd began to happen:
Each time I open an application, it opens three times.
Click on Firefox -- three Firefoxes.
Click on Rhythmbox -- three Rhythmboxes.
I'm sure I did something stupid, but I have no clue what it might be.
UPDATE: Applications Open Multiple instances
On a closer look, I see that applications are not opening three different *instances.*
They're opening three *icons* in the lower panel.
I can minimize or maximize or close an application from any of the three icons and all the rest go away.
So, it's mostly annoying, I guess.
But it's *really* annoying.
