Just came back from test center. I got the computer problem saying "out of resources" when I began the question 172, which is a drag'n'drop question with a large image. The guy in the enter restarted the computer but didn't solve the problem. Then he called the prometric and was told to switch the test from Win 98 to Win 2000. Everything was good since then. So don't choose Win95/98 to do your test. Good luck.
Jack, I think we are not able to choose the computers. The test seems to be running on some above-Win95-os, but the interface looks like good old Win3.1. That is one point. Another, more important one is when you arrive at the centre, they will prepare everything in advance. That was the case for all my exams with Prometric - they just knew the times from the morning download and fired up the pre-loaded tests at once. Ironically enough, today I didn't take the originally designated machine. The secretary just told me the original computer was for some reason re-scheduled and they moved me to another one. So, when you see the 'wrong test computer' message, just ignore it and continue. But this everything was handled even before I arrived at the centre. So, we came in, checked the Prometric ID and off we go... I don't see any way to choose the computer. Only if you call in advance and explain the problem faced, but I guess Evelyn is working right on this issue. Anyway, thanks for the suggestion
