Cell selection bug in subwindows

There is a bug where you cannot select a cell in a table properly when the table is in a exterior subwindow.
This happens when I have two tables in panels, one in the main window (panel) and the other in the exterior subwindow (panel).
I need to click a cell twice to get the selection right when switching from the sub to the main window.
It's great if this can be fixed because I like having a subwindow with a table on it.
Please create a simplified experiment showing the problem and send it to WaveMetrics support.
