RE: [linrad] Linrad Questions
Hi Roger good evening,
I woke up a little late this morning and saw good news from both of you!
I will try first download Leif's new one and next yours.
I will give you informed shortly.
Almost two years lovely grand son will visit us this week end so I'll be
busy some, Hi:-)
Also, I have recently finished the evaluation of RedHat 8.0 which ended
up badly I will report this to the reflector.
Maybe some chance with lir00-48?
More later, thanks anyway,
