Well, I played with Glom quite a bit today. I was able to get all the examples to open except the Film example. However, I was unable to see a pattern in the opening process. It seemed hit and miss. I think the program is not working right but don't know for sure. It might be that my unfamiliarity with postgres and linux databases generally (I still use dos foxpro 2.6) is the main problem. Would be great if someone with more familiarity with glom would give it a try. I am pretty sure that the example databases can be opened, given enough tries and a little luck.
And, its possible that the program itself has bugs. Again, would be great if someone who has used Glom could tell us what is going on in some detail.
I am probably the worse person in the world to be saying this, but I think the install still needs a little tweaking.
