Hi
Eddie,
no problems with freezes from that SpecLab version here so far.
But I do find that Windows10 is not quite kosher regarding continuous
operation. I'm running the slow VLF stuff on a convertible laptop under
Win10 Home. Within a week or so after a restart, memory usage gradually
creeps up from ~ 45 % to 85+%. At that stage, the PC becomes
practically inoperable and needs to be rebooted. If I can still manage
to shut down SpecLab instances cleanly, saving configuration data can
take many minutes instead of a couple of seconds. Such things never
occured on the faithful XP machine which is still hosting the LF and
Loran grabbers.
To prevent a loss of weeks and months of slowly aquired
spectrograms, you could enable SpecLab's file-buffer, which should
preserve screen content through a restart (see attached).
Best 73,
Markus

Yes that will be worth a try, I should have a stable set up ready, I
have had a display freeze on my EbNaut instance so I shall miss the
Sunday night transmission.
I think Speclab v2.92 b02 suffers from display freeze, I used to run 8
to 10 instances without problems now the 4th instance seems to produce
problems and one of the instances will or may freeze, not necessarily
the last instance or an intensive (20uHz or 5uHz) one either. I wonder
if anyone else is experiencing this.
I have seen frozen displays still exporting updated screen captures
too,
a case of WYSINWYG (what you see is not what you get).
It is a very difficult thing to test because of course I don't want to
induce it, the processor load is only 15% with 4 instances running.
