I have the SVN Version 2009-Jan-28.
Further on everytimen i open my *.grc file, the <grc> deletes the manually
inserted class-method,
<set_sample_rate>
so there must be a Problem.

Yes i will try this and post the message here.

Another important Point,
Is there a possibility to save my manually inserted python commands
in the <top_block.py> file without loosing this by the next
start of <grc> ?
