Hi again,
I've been buried for the last month with a conference, following up from the contacts at the conference and the work we didn't get on with becasue we were at the conference. 
We did quite a lot of demoing grass and vis5d at this conference (mineral exploration and mining) and were very pleasantly surprised at the strong positive response we received from industry.
This last week I've been re-syncing with the latest source to get back to working on testing and fixing. As I was reading through this list I noticed HM and GC had been asking about some of the changes and testing. Couple of comments:
1) When I synced to the current source and built the g3d utilities I found that the two I submitted changes to were breaking the build. It seems that the way the changes were submitted resulted in a version comparison getting into the code tather than the change.
2) After I "fixed" the current source and rebuilt it - Top and Bottom and being reversed when I view the result in vis5d. (Originally it was T-B and N-S being reversed.) I'm puzzled about this and so far have not found the problem. Its particularly puzzling since we were successfully demoing this over the last month. This is quite a high priority for us so I will be focusing on this and other g3d testing in the next while.
3) We needed to import some MapInfo mif files and so I've tested and fixed some of the problems in v.in.mif. The import is working and we are using it, but I have one more bug I need to track down before I sumbit fixes. The changes are small and minor but the errors resulted in bad file names and seg faults.
Glynn: shall I send them to you as diffs the way I did before?
