Why doesn't IE7 copy blocks to the clipboard correctly?

Answer 1

Here's the issue:

Your code colorization script replaces line breaks with
tags. When copying/pasting, IE7 apparently doesn't translate the
tag into a linebreak like it does for the screen.

In other words, your code becomes this:

public PageSizer(string href, int index)
{
    HRef = href;
    PageIndex = index;
    }

But you want it to become this:

public PageSizer(string href, int index)

{

    HRef = href;

    PageIndex = index;

}

In the latest version of prettify.js on Google Code, the line responsible is line 1001 (part of recombineTagsAndDecorations):

html.push(htmlChunk.replace(newlineRe, '
'));

Edited, based on the comments:
For IE7, this is what the line should probably be changed to:

html.push(htmlChunk.replace(newlineRe, '\n'));

(Assuming newlineRe is a placeholder).

This fix also holds up in Chrome, and FFX3... I'm not sure which (if any) browsers need the
tags.
