Semi-OT: Strange behaviour of the letter "L"

[Alneyan]

Hmm, let me see... I *saw* the grey boxes, but they have now disappeared. It has been at least a few months since I last saw them, however. I was on Firebird or an early Firefox release back then; I am now using Firefox, and the grey boxes are no longer here.

A Spell of Greater Purging has been cast since then as well, so perhaps it solved the matter (that spell is better known as "HD crash, roll Fortitude or lose all your data. DC is 30"). Still, I would believe Firebird is responsible for those grey boxes, and nothing else.
