I know you are not a decision maker in these handling practices and therefore it is unfair that you get the complaints, but If I were "Mr. Photopost", I would make sure that all very basic and standard features are working correctly with every integration you are offering BEFORE releasing it as a non-beta. (and It was reported, that this is also with fresh installations by the way).
Basic functions are: Displaying of images & comments, upload/delete/move/ an image, e-mail notification, registration etc.
This takes about 30 minutes to test and I would expect photopost to do this for every release they offer since they get our money for the product.
The severity of a bug is not declared by the easiness of the fix. It depends on the consequences for the costumer. To have a gallery which does not display any comments suddenly is not minor at all. But I understand now that this was not a rating made by photopost.
It is just a matter of fact that I get angry, if I have to invest hours of my time, rsiking relationships with my users, just because basic functionality was not tested enough. I payed for the software but I do not get payed for testing this.
I am fine if there is a bug which is not that obvious or important in the consequence and not easy to test. But in this case, my tolerance is very small.
Again this is not meant for you, but I guess you know this
