 I have no (direct) problem saving an event that spans midnight (local time). I
just have to go thru a little more to do it. First I'm using V2.7. My usual
routine is to replay a time window which spans the event. I then go back and
save the same. The problem I encountered was when I tried to replay a time
window which spanned midnight the computer plotted the time til midnight and
then said "End of file-  Press esc to quit , S to save data, N for next day".
The S option gives an "err : unable to save data- press any key ". Only esc
works. The way I got around this was to -replay- a time window that stopped
before midnight( say only 10 min) so I didn't get that message, but -save- the
time window I desired (say 80 min).  I have the "UTC" offset set to -8. I don't
know if this has anything to do with it but  I can't seem to be able to free
enough conventional memory to run DOS while in SDR . It is perhaps that I am
running 5 channels @ 25 sps with a 5min save before and after the trigger. The
program is great as it is. I only brought it to you attention for your use.
