What´s a draw buffer?

[carambole]

I´ve been trying to add some extra units to a scenario, in which I´ve also added a new civilization. I´ve put in all the extra files, like pcx-files in the Civilopedia directory, and created new folders for the units in art\units with animations and suchlike. I´ve also written in references to the pcx-files in the PediaIcons text-file. But, it doesn´t work. The new civilization works allright, but when I try change production in a city the program says that it can´t "allocate draw buffer" and then it shuts down. Now, I´ve been searching through all the folders, but I can´t even find the phrase 'draw buffer' anywere!
Can someone help me out?

Let me guess... you have an ATi video card?

I had the same problem. Go to ati.com and update your video drivers. That should solve the problem.
