Markus,

I really believe that the gui is not freezing. What you see is a result 
of the fact the the peak detect outputs a binary 1 or 0 signal.

Connect the peak detect to a char_to_float block, and then to a 
numbersink. Setup the numbersink for a min of 0 and a max of 1. The 
numbersink will clearly show what state the peak detector is in. Make 
sure to include a throttle somewhere.

Take a look at the source code for peak detect, perhaps the comments, or 
the implementation can help you to figure out what the parameters like 
threshold or alpha mean. Also, add a few printfs to the work method, to 
verify what the block is outputting, and if its really freezing/stopped 
working.

Hope that helps.
