[hpsdr] Interesting problem with WSJT

I commented a few weeks ago, that I could not get WSJT to run properly with my 1 watt SDR1000, in that it would crash quite quickly after
starting, and I could not find the answer.
I now have my Atlas/janus/Ozy board running and controlling the SDR1000 and miracles, WSJT appears to be stable,
so far it has been running for a couple of  hours monitoring /showing the RTTY contest activity on 20meters.
wth a very good waterfall, (I wish other programs could match Joe Taylor's WSJT )waterfall. Sure it is optimised for EME but it is easy
to see signals.
Today I set the background noise level as 1db on the WSJT screen and it varies upwards from there, depending on the strength of the incoming RTTy signal.
Whereas before it would be set at 1db and then take sudden dives down to -20db which completely ruined the decoding.

Can someone please,  try to enlighten me why, WSJT should be more stable via the Atlas platform, than on an XP computer
or am I dreaming and it is just plain dumb luck.

Best wishes to all
