Hi Mathieu,

Thanks for this, I have done a trace back with the following output on the terminal :

Also Gridflow as mentioned previously causes crashes but not so hard as py.  When I swapped the L2Orkt file to normal extended, I could use Gridflow in the new gui as normal- so perhaps the issue is not in the tk file but else where?

If you (or someone else) can narrow down the l2ork<->gridflow problems, I could try to fix them.

Is it something happening mostly with the helpfiles, or also with something else ? Is it happening at startup, or later ?

What is the "L20rkt file" ?
