- We had major view problems with Ingres version "6.4/01 (dg8.us5/01)" on a
- DG Aviion. Ingres acknoweledged that there were some major view bugs in
- 6.4/01. When we upgraded to version "6.4/02 (dg8.us5/00)", all the view
- bugs disappeared. If you can get a 6.4/02 for your Sun, then get it as soon
- as you can.
