Dockable Window does nothing if floated and docked with custom window

[w.pepping]

Hello,

I have a strange thing with my dockable window. If I undock the model window and dock my custom window to this model window, the model window does not react anymore.

This only happens if both windows are docked to each other and are floating, and 1 of the windows is a custom window.

Only the standard windows are 'locked'.

Hi Wim,

The windows form needs to been showdialog vs show!

In a dockable window the child dialog should be always 'show'.

So that solves not the problem for me.

I found that the windows are acting normal after clicking on the 'Home Tab'.
