Bump.

I'm wondering am I the only one this happens to?

does it make a difference if the multidock is on your primary monitor? i seem to remember previous posts about 2nd monitor issues?

Will check about 16:30 BST busy until then.

At first I thought it did. But in my tests I found as long as the multidock is undocked, it'll do it. At fist I thought that the undocked multidocked window had to be maximized. But it's happening even with the multidock floating on the first monitor.
Again wookie, thanks for trying.

I went ahead and made a problem report on it to see if they can reproduce it.

Just been having a little play, got distracted by the sound I was making sorry.

Well I was having fun.

I still am unable to recreate your problem.  The report is a good thing to do though.

Hope you sort the problem.
