[wxpython-users] wx.PopupMenu hangs during execution

I have an issue in an application I'm developing, and I'll try to create a
standalone script of the issue (won't be easy), but I thought I'd describe
the issue here to see if something sounds familiar. I have a matplotlib
canvas with two matplotlib events programmed to bring up popup menus. In
general, I have no problems bringing up the menu and running something off
the menu. However, often I have to click several times to bring up the
menu, and my traces show that for every click, the code goes as far as
wx.PopupMenu() and seems to hang up somewhere in the execution of
wx.PopupMenu.

A second issue is that I have two different popup menus that are brought
up. One popup is brought up by a right-click, and the other is by the
matplotlib selector widget. If I can bring up a popup with a right-click
and select a menu item, and then use the selector widget to bring up the
second popup menu, I cannot ever bring up that menu, and again, the code
executes as far as wx.PopupMenu and seems to get hung up somewhere in that
execution.

My general code for popup menus:

menu = wx.Menu()
.. add menu items using menu.Append
self.PopupMenu(menu)
menu.Destroy()

I've tried binding PopupMenu() to the frame containing the matplotlib canvas
and also to the canvas itself.

any reason why PopupMenu() would hang?

for what it's worth, if wx.PopupMenu hangs, and I close down the
application, I can't get a cursor at the terminal window

using wxPython 2.8.8.0, matlotlib 0.98.1, python 2.5.2, debian testing box

thanks,

Paul
