Mouse Event Error

[Zed Lands]

Greetings Pythonians,

I got two sash windows. On the left window there is a tree,and on the right window there are some checkboxes.

Neither of the two sash windows respond to the mouse click event (EVT_LEFT_DOWN) although the checkboxes can be triggered. Yes, the checkboxes can be triggered without using the mouse click event.

How do I make the sash windows respond to the mouse events?

p.s.Both of the sash windows, when they run in separate files, they both respond to mouse events.

Thanks
