Docking the Assembler window results in it to be no longer useable

Description:

I really like the docked IDE. While debugging assembly code however it's a bit annoying that the IDE comes into foreground of the Assembly window each time. To solve this I thought I'd simply dock the Assembler window, but once I did that it became completely unuseable, displaying only one line (that still can be scrolled). This even persists when I undock the windows. I need to reload the project or to restart the IDE to solve this (no matter whether the windows is docked or not).

Steps to reproduce:

Start the IDE with installed Anchor Docking
Open the Assembler window and dock it
Instead of displaying multiple ????? lines there will only be one
Undock the window and it continues to be so
Reload the project (either with (4) done or not) and the Assembler window will be correct again (until the next docking operation of it)

Additional information:

Attached are two screenshots. One shows the docked Assembler window and one a freshly undocked one.

The version is 1.6RC2.
