bug#15261: Re: bug#15261: 24.2; Cursor not visible while moving point in transient mark mode

[RICHARD MUNITZ (BLOOMBERG/ 731 LEXIN)]

When I log in to the Solaris server through a PuTTY client, I do not experience 
the problem.  The problem does occur within the Exceed X terminal window if I 
start Emacs with the -nw option.

Does the problem happen for you when you run Emacs locally on that
machine?  Or does it only happen in this particular configuration,
when you use Exceed to access a Solaris server from a Windows machine?

Comparisons with gvim are meaningless, because there's no primitive
"highlight this text" operation that both Emacs and gvim use.  Each
one of them highlights text using very different methods.  In Emacs,
the portion of the text that is highlighted is actually fully
redisplayed.
