Hi Everyone,
This is my first post, so I'll apologize in advance for any inadvertent lapse in manners.
I'm using matplotlib 0.98.5.2, wxPython version 2.8-msw-unicode, on Windows XP Professional x64 at work (and 32bit at home). At work I have a plain old Dell 2 button mouse with a scroll wheel which you can scroll or click as a middle mouse button. At home I have an equivalent mouse from Logitec. Both mice exhibit useful functionality for the "middle button" in browsers. And I did install the latest Logitec drivers at home and specifically set the scroll click to have the functionality of a middle mouse button.
In all cases, home or work, I failed to detect a middle mouse button press or release event.
I've attached an example program and copied the text below.
If anyone could please check to see if this is happening for them, or has any idea how to fix this, I'd very much appreciate it.
Thanks,
