Comment:

Here's a stack trace. Looks like something's triggering drag-n-drop.
I've noticed that dragging onto various widgets seems to crash Chandler on
OS X, but last time I checked not on Windows, so this may be the same
issue.

What I'm doing *shouldn't* be triggering drag'n'drop, but I haven't
succeeded at building a Python with symbols on Leopard yet, so I'm not
quite sure what's going on in Chandler's Python code yet.

Comment:

Hi Jeffrey

why do you think it is triggering a dnd ? (I've opened a ticket for the
dnd problem at #9748 btw, to collect evidences that might help me to
reproduce it)

which wx version is this based on ?

Thanks,

Stefan
