I have recently upgraded from 6.4.1 to 6.5. I first planned to wait for 6.5.1, but I really needed to get this done now.
I really like 6.5. Among lost of new cool stuff, it has had a huge improvement on server load. 6.4.1 was really down on it´s knees during the busy hours of the day, but 6.5 is really jumping.

But there is one anoying bug. I am having trouble with sending PM:s. Both for myself as an Admin and for some users.
The think that happens is that when I click send Threads just says that the username (the recipient´s username) do not exist.
Replying to a reived PM works just fine, so I don´t think it is the PM Quote Original Message 1.4 mod I have installed that causes this.
I guess this is a known bug?!
Does anyone know how to fix this, or do I have to wait for 6.5.1?
