Anybody see this before? I opened up Terminal.app and the window is completely blank. There is nothing in it whatsoever. Looks as if bash never started. The title bar simply says "Terminal — login — 80x24". I can type whatever I want in the Terminal window like it's a text document and nothing happens. If I restart the computer, this seems to fix the problem, but it seems to only be a temporary fix as the issue happens again soon after. Any ideas?
