Re: Nov 10 Release

["guyhm2002" <guyhm@xxxxxxxxxxx>]

David/All,

I've just installed the Nov10 release on a W98 machine and a W2000pro 
machine hoping to see if the problem I described in 1420 had 
disappeared.

Unfortunately it might have got worse. On the W98 machine the editor 
works fine, as does triangle, but fkern generates a page fault. On 
the W2000pro machine the same thing happens with an access fault. I 
suspect they both point to a memory problem?

Has anyone else seen this problem? Perhaps it's something to do with 
my environment or the problem I was trying to solve?

David, I have the error report from the w2000 machine, where do you 
want me to send it?


Regards
Guy Mason
