I don't know if it was Poser 5 or Poser 6, but, in one or other of them, Open GL clashed with my display driver.   If I moved the cursor over a figure, bodyparts, or the whole body, would vanish for a few seconds.   Then, at last, a driver update came along and the problem was banished to the outer darkness.

A few weeks ago, I tried to install a demo version of some software and found that it wouldn't even start.   I hunted down a device driver and I was able to start the application and run it.   Odd thing, though:  I had to re-install the device driver, every time I wanted to use the prog.   Then, yesterday, I discovered that even this wheeze no longer did the trick.   The software just wouldn't run at all.

I located another new driver and installed it (having to install a bunch of MS updates for compatibility, against strenuous efforts from Windows Update not to let me have them).   At last, it went on and the software did a Lazarus.   Everything was fine.

Then I started Poser and thought it was a bit strange, the way half of Terai Yuki vanished, whenever the cursor came close.   Strange, but strangely familiar, too.

So I suppose this isn't entirely OT:  how much do I lose out by using SreeD, instead of Open GL?   It's mainly Poser 7 that I use now.
