(Sorry, I posted in the forum on https://garage.maemo.org/projects/zutun/ before I found this.)

I had the same experience as nef919.
I am also running 4.2008.36-5 on an n810.

Is this a generic problem with python support on the n810 not allowing application switching? (I have no idea, I don't know anything about python.) I've noticed that even before I hit the "OK" button to bring up the RTM page to authorize access for Zutun, I am unable to switch to any other applications. If I hit "Cancel" instead, I go right back to normal operations.
