[rdesktop-devel] Re: Problem with delete key and notepad

[Roger H. <rog...@nt...>]

I now think it is a problem with the X Server.  Some of the text commands
recieve a clipbox Cx parameter of 32665 or so.  I have added a line in
orders, in the text routine, to say:

if (cx > 0x400) cx= 0x400;

This appears to fix the problem.  I have not fixed the other places in
orders where clipbox parameters
are passed in.  The problem has now been seen on notepad and also the CA
Openroad editor.

(Apologies for not giving a more exact reference, I am collecting all
changes together, but the system
I am testing on is not connected to the internet and there are some hurdles
to getting the source
out of VMS format and compared back to the original source.)

By the way, when making changes using preprocessor directives for VAX VMS,
what should I
be defining.  At the moment I an using
#ifdef _DECC

is this right, or is there a better convention to use?
