freezing problem seems to be solved now, many thanks
response time seems a little bid higher than before, but hightest values are 400-430ms what is at least absolutly fine, no artefacts any more
Today is December 22, and no other posts except of yours. No problem on any server. Check your internet connection. I think, the reason for your freezes is internet.
