Details

run apprunner -editor in test page, select "next paragraph is a block" make bold (Ctrl-B) this causes the text node containing the selection to get wrapped in a "B" span. notice that the text doesn't repaint unless you cause a reflow (but don't do this yet.) right arrow. notice how poorly the line paints. once you've arrowed over all the text, the line has painted correctly.

Well, I can't reproduce this: (1) it renders correctly the first time for me. (2) the arrow keys (on linux) work exactly once. The second key (either direction) does nothing. Back to you steve...

The OS is set to NT. It still happens on NT as of debug built from code at 4:00pm today. I see this on 2 different machines (work and home, both NT) Back to you...

This might be a dup of 4593. Kipp and Mike should talk and come up with a strategy for attacking this problem so they don't duplicate effort. In private messages, Kipp has indicated that this doesn't happen on Linux, and probably isn't a general text update problem. Selection is the next most likely culprit.

adding test case, because the editor test page has changed. <html> <head> <title>Ender Startup Page</title> </head> <body bgcolor="#FFFFFF" text="#000000"> <h1>Welcome to the Gecko Editor Test Bed</h1> <P>This next paragraph is a blockquote.</P> <BLOCKQUOTE type="cite"> Lorem ipsum dolor sit amet, consectetaur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

[There is no one who loves pain itself, who seeks after it and wants to have it, simply because it is pain.]. [de Finibus Bonorum et Malorum, written in 45 BC, is a treatise on the theory of ethics very popular in the Renaisance.] </P> <P> "What I find remarkable is that this text has been the industry's standard dummy text ever since some printed in the 1500s took a galley of type and scambled it to make a type specemin book; it has survived not only four centuries of letter-by-letter resetting but even the leap into electronic typesetting, essentially unchanged except for an occational 'ing' or 'y' thrown in. It's ironic that when the then-understood Latin was scrambled, it became as incomprehensible as Greek; the phrase 'it's Greek to me' and 'greeking' have common semantic roots!" </P> </body> </html>
with code from 4/20 late afternoon, I no longer see this problem.
apprunner was not necessary for this bug, it was also possible to recreate this bug using the test case in viewer.
