I'm aware of the issues with the dark theme and I'm sorry they have been around for a while. Actually there are a number of other problems with the dark theme as well. Each time I upgraded vBulletin recently a few more issues with that theme popped up, and that was part of the reason for going to a new theme back when we made the switch to the new default light theme.

The developer of the dark theme disappeared, so I haven't had anyone to fix it. With all the other problems popping up with VB updates I was not able to fix it myself.

Since you guys are using the theme regularly as your default I'll see if I can track down the developer, or if anyone has experience working with VB styles and wants to have a go at it send me a PM.

If nothing else, I'll give it a go myself when I have some time, but it's not going to be very soon I am afraid.
