[pygtk] ComboBox problem

[lcrocker]

My app works perfectly, but it behaves differently when I run it on
Windows:
On Linux, I click on the ComboBox, and it pops up the list; I browse
the
list, then click to select.  On Windows, I press the mouse button on
the
ComboBox, and the list pops up; but if I release the button, it pops
down
immediately, whether or not I have made a selection.  I have to hold
down
the mouse button while browsing the list, and the selection is made
when
the mouse button is released.

I don't see a setting for this anywhere. I want the Linux behavior.
Menus
work the same on both platforms; it's just ComboBoxes that seem to
fail
on Windows.
