I agree this is an issue with Dolphin 6 as well you would install a release on your website that would have one two or three bugs, the next version would promise a fix and would actually fix 1, 2, and 3 but would then break a whole new set of features. So another version is released and bugs 1, 2, and 3 are back. This is just an example.

Dolphin 6 IM works, dolphin 6.x IM no longer works, dolphin 6.1.x IM is fixed again, and then bam 6.2.x IM feature is yet again broken. This seems to be a see more repeating problem with this software, I am not a programmer so I won't pretend to know how to fix bugs etc, but I have worked with other Open Source Projects in the past that when a problem was fixed it stayed fixed, it didn't keep creeping up again and again.

Please note that above I used versions that may or may not be valid, it was just to serve the purpose of further explaining what I was saying, if you feel the need to comment on how I know nothing about this software based on the above statements you can keep them to yourself, the information about the im is only an example.
