Bug: Getting dice from random.org for the second time

[Peter Lederer]

Hi guys,

I use GNU Backgammon 1.06.001 Feb 28 2018 on Linux Mint 19.3 as it
comes from the distribution repository.

As dice generator I use random.org. The fetching of the first 500 dice
works fine. When required to receive the second portion of dice it
says "Your dice generator isn't working. Failing back on
RNG_MERSENNE". At the same time the dice settings jump back to
"Mersenne Twister" and stay there.

It would be helpful that GNUBG fetches all of its dice from random.org
as it is the only real random dice generator.

Thx for your work.
