thank you very much. when i ran it first, it gave me error, python not installed, but i think when i installed the app, python and other packages were installed also. but anyway i did apt-get install python. it installed two files python-minimal_2.5.2-3maemo4_all.deb and python-2.5.2-3maemo4_all.deb.

Now when i entered the command u gave in terminal again, it says like this, Maemo application must be run with the run-standalone.sh script! QGTkStyle was unable to detect the current GTK+ theme. Segmentation fault.

Btw have u run the app in ur n900 successfully?
