Has anyone else noticed that after you play for a while (Usually around the 1 hour mark for me), you can no longer pause the game?

I thought it was related to the 'plzsutekcanihavemoretime' cheat as I usually could pause until I entered that. But today after I screwed up on the first game at about 25000 points and an hour of play, and submitted the points I noticed that immediately I could no longer pause in the second game.

I am currently stuck at having to wait until the board reshuffles so I can pause.
Any ideas - I submitted it to NeoPets as a bug/error but am wondering if it just me. Yesterday I had nothing clicked but as soon as I tried to move anything it would do the error noise and not allow me to make a move - no message at the top which usually appears when you try an invalid move - just short of what I needed to get to end up with a trophy.
