SWAPdmt error - Gdk-CRITICAL

Hi Daniel,

I'm trying to run the SWAPdmt GUI but I'm having some problems. When I execute (in python_tools-3.1.3/swapdmt) "python pyswapdmtgui.py" then I get the following error message:

"(pyswapdmtgui.py:2175): Gdk-CRITICAL **: IA__gdk_window_get_origin: assertion 'GDK_IS_WINDOW (window)' failed"

I'm able to se the window of the SWAP Device Management Tool but I can't see the options "File", "Gateway", "Devices" and "Help".

Do you have maybe any clue about what I'm doing wrong?

I've tried installing different versions of GTK+, wxpython and python_tools but nothing

thanks!

by the way, I'm using Ubuntu 16.04.2 amd64
