Q. Why does TerminalApp take so long to start up?
A. You probably have lots of fonts installed. TerminalApp builds a font list on startup. Remove some fonts or use a FontManagement utility.
Q: Why does my monospace font appear to shift around when I use the arrow keys to edit a commandline in TerminalApp? Is this a bug?
A. Yes, it was a bug in Mac OS X 10.1. It was fixed in Mac OS X 10.2 (Jaguar).
Q. How do I make the TerminalApp window translucent?
A. TinkerTool.
