Thanks to Jon for pointing this out and proviing further details. I now have a
fix for this problem, whereby what caused a busy wait on some operating systems
will actually stop xpp responding to the user on a recent Debian release. I
have attached a patch which should work on any version downloaded in the last
18 months or so.
To use the patch, copy it into /tmp say, then go to your ProofPower build
directory (where config and install live) and do:
gunzip -c /tmp/patch-2.9.1w2.rda.120821.gz | patch -p1 -b -B orig/
then do:
PPTARGETS=xpp ./configure
./install -d
Regards,
Rob.
