[A6] freezing up/ strange displays

[Leo Schoutrop]

some weeks ago there was a small discussion on the  fact that  b.e. tweaking
around the buttons / doing a heavy means of editing might freeze  up the
andromeda. 
i experienced this  quite a few times now ( not such a big deal, as it still
remains the best synth i have ).
i  really would like to know if this is a common function on the andromeda ?
 so are there people out there who NEVER had a problem of freezing up the
andromeda??
