Hot Windows: sometimes won't open

Sometimes a specific hot window won't open. In my case it's the transform window (in fullscreen mode).
here's my config:

What is the title name of 'transform window' you said?

If the window is docked or autohide or visible, the hot window operation won't work on it. This is intended not to break your docking setup.

If I go to View-> Toggle Fullscreen, there are no more windows visible. I then bring up my radial menu with the hot window entries. The name of the entry that isn't working for me is "Transform List Window" which should open "Transform List".

Fixed.

I now get an error message when calling transform list window. After that the window opens.
It's also possible to open the hot windows, while the window is open/docked. They go blank for the time being. I like that. (Though I able to break it, but couldn't reproduce yet, so I keep an eye out.)
