That is what is happening.

It happens with both qt application I am using.
The problem seems to be that those are not setting the _NET_WM_PID
property on their first and main window until after creating, but 
on the transient windows opened later.

Having two frames I select one of them, start the program with
the exec comand there. The main window opens up in that frame.
I select the other frame and let the program start a transient window
clicking there with the rat. Then it opens a window, but that window
shows up in the frame the original window was and not in the one
currently selected.

Some snippets from the .xsession-errors of ratpoison compiled with

        that's _NET_WM_PID, I guess that needs handling here,
