I tried to use Babylon (http://www.babylon.com/) with Emacs, and found
that not only does it not work, but Emacs actually crashes when I use
the ``Babylon click'' on one of the words displayed by Emacs.
The backtrace produced by DrMinGW (attached below) seems to indicate
that we get a WM_PAINT message that we somehow cannot grok(?). Is it
possible that Babylon sends us WM_PAINT so that we draw some part of
our screen in a DC that isn't ours?

I get this backtrace.
(BTW, how do you set drmingw to get such detailed backtrace?)

Thanks. I'm no longer sure that my assumption about WM_PAINT was
correct. I don't have Babylon where I'm typing this, so how about if
you try to see what message(s) Babylon sends us? For example, using
Winspector (http://www.windows-spy.com/).
> (BTW, how do you set drmingw to get such detailed backtrace?)
I don't see that my backtrace is more detailed than yours. Note that
in your case we are deep inside system DLLs, where debug info is not
available. For our functions, you get all the arguments and the
current line, AFAICS. Am I missing something?
Anyway, the only gotcha with DrMinGW I know of is that the program
must be built with -gstabs, as it seems not to support DWARF-2 right
now.

I've been trying for a while, but I don't see anything unusual. In the
last few seconds between the Ctrl+Rbutton and the crash Emacs received
the following messages:
WM_GETTEXTLENGTH : 52 times
WM_NCHITTEST : 31
WM_MOUSEMOVE : 30
WM_SETCURSOR : 30
WM_USER + 7174 (0x00002006) : 26
WM_GETTEXT : 26
WM_USER + 20 (0x00000414) : 17
WM_NCACTIVATE : 1
WM_WINDOWPOSCHANGING : 1
WM_ACTIVATEAPP : 1
WM_MOUSELEAVE : 1
WM_WINDOWPOSCHANGED : 1
(I can send you the XML dump with the timing and parameter/return
value info, if you want.) I don't know what the WM_USER + 7174 is, but
the rest is more or less as expected. (Well, the barrage of
WM_GETTEXT(LENGTH)? messages is unexpected, but I think it's just
Windows trying to make sure it got the window title right.)
Curiously, I don't get always similar info from DrMinGW, though most
of the crashes are like this one:
emacs.exe caused an Access Violation at location 7e3b1690 in module
USER32.dll Writing to location 7e39f7f9.

You're right. I don't know what was I thinking...
