bug or what?

having a little problem with lamps in blender.
whenever i add a second lamp to my scene, select it and then select anything else, blender crashes.

any ideas what´s going on?

edit:
well, actually it even crashes with only one lamp.

do you have an intel graphics card?

get the latest drivers, and run at 16 bit [high color] instead of 24 or 32 bit [true color]

this isn’t a blender bug

no, i´m using a notebook with an ati radeon mobility 9700
