I use the U key on my laptop to go up/back a level in the SDMB.  
Today it appears to not work most of the time.. Eg, I’m in MPSIMS reading a  
post.. I hit U to go back up to MPSIMS, and it goes to the post in MPSIMS  
I was reading before. Hitting U again goes back to the main categories page.  
Very annoying.
