Could you post an example instruction that fails for you and can you
describe how it fails?  It is difficult to give any opinion without
these data.

Drawing a plot using line() commands is a lot of work.  Is that really
what you are doing?

Have you tried to specify the properties in the line command?

 -- Function File:  line ()
 -- Function File:  line (X, Y)
 -- Function File:  line (X, Y, Z)
 -- Function File:  line (X, Y, Z, PROPERTY, VALUE, ...)
     Create line object from X and Y and insert in current axes object.
     Return a handle (or vector of handles) to the line objects created.

     Multiple property-value pairs may be specified for the line, but
     they must appear in pairs.

Well, if the same commands work on a platform and do not work on the
other, yes it is a platform-related issue by definition :)

Unfortunately I cannot help you here, as I have no experience with
Windows.  However, you can try to have a look at the mail archives and
look for Windows 7 discussions.
