I used this to quickly enable me to continue working on my thesis (involving some python coding), while migrating to emacs. I played around with this issue again today and found out, that it doesn't happen if i comment out the initialization of the python setup i mentioned in my .emacs . So I guess its some incompatibility introduced in this package. I think I'll abandon the package and create my own setup when I find the time to do it. I guess this issue doesn't have anything to do with org-mode after all, I'm sorry for any inconvenience I may have caused. regards, Dirk.
