So, I recently got a bit tinkerish with my new Quicksilver update (it’s back!!) and ended up stubbing my toe. For some reason whenever I switched into an application, all of my other applications would automatically hide.
I thought, “This is kind of cool,” since I have a pretty great desktop image that I rarely get to see.
But within a short amount of time not being able to see the background windows got wonky on me… I needed to see that to type into terminal, or textmate, etc.
So, I looked and looked to no avail… then I went back into my Quicksilver settings and caught this lil’ treat:
“Hide other applications when switching (Shift prevents)”
In my exultation I clicked this one… I shouldn’t have. So, If you have this problem. Just uncheck that lil’ guy and you’ll be golden.
