ToME: the Tales of Maj'Eyal

Hi, just starting with TOME... The Inventory screen is a bit unwieldly in a few ways, but is there a way to change how the tooltips work? They pop up with a mouseover, but don't go away with a mouseout. They don't seem to go away until another mouseover event. Can I configure somehow to get them on rightclick or something besides mouseover? Or should they go away on mouseout?

And light radius... Am I missing some obvious means of expanding that beyond 2? I hope so 'cuz that's pretty claustrophobic.

Anyway, thanks for the newb help.
