The op did not supply enough info for you to help them resolve their query...

No need to spend time answering a question the info you reckon they may be relating their question to. I also reccomend avoiding further reflective anguish by previewing your response in your personal scratchpad before posting. It does take a lot of experience to really distingiush the probable info they refer to, and even then its usually a waste of time as users will inevitably have some unique variation that overode their laziness directive into asking the question in the first place.

Also on *Nix type systems you can get a full screen shell window with the Alt+F7 key combo, something akin to Alt+Tabbing on Dos type implementations.
