Hello Bernhard,
thanks for pointing this out.
The "page refresh" is defined and performed by the following line:
>> &Header::openbox( 'Waiting', 1, "<meta http-equiv='refresh'
content='10;'>" ); <<
This kind of refresh logic is untouched and worked well since many
years. The "http-equiv" tells the browser to do a refresh of the page
and the content contains the amount in seconds to wait. (See more
here: https://www.w3schools.com/tags/att_meta_http_equiv.asp)
I didn't noticed any problems with Firefox as browser on various
linux distros.
A very easy test would be to decrease the time interval (minimum is
"1") to force more periodic page reloads and check if the log output go
further.
If everything works well we may need to think about a new interval
value because 10 seconds nowadays may be to long for the high speed
hardware out there.
Best regards,
-Stefan
