[wxPython] different right double click behavior

Hello,

I've noticed a different behavior on Linux and Win32 when right mouse button
is double-clicked. I'm intercepting both right-click and right-double-click
events. When right button is double-clicked on Win32, there is one
right-click event (i.e. function is called) followed by right-double-click
event. On Linux (Redhat 7.2) there are two right-click events followed by one
double-click-event.

I'm using wxPython ver. 2.3.2.1. Is this a bug or some gtk feature I'm not
aware of?
