Actionscript:   / HTML text issue from an old Flash 8 project

I built a project back in 2006 that's amazingly still alive and making lots of money for a client. I had a bit of code that would insert an   into a textfield for dummy spacing in between other letters. Out of nowhere, this stopped working for the client, and all the text was space-less. This is what I had:

StringUtil.searchReplace( myStr, _dummyChar, '<span class="textDummy">&nbsp;</span>' );

This now fails to insert a space. I tried just using an actual space, but since this is an html textfield, multiple consecutive spaces don't keep making more room. So, I added a space after the  , and magically, it works like it had in previous years:

StringUtil.searchReplace( myStr, _dummyChar, '<span class="textDummy">&nbsp;</span> ' );

Whew fun!

ActionScript: Random number function

I saw that one of the top results for "actionscript random number" in a Google search is incorrect, so I figured it would be a good idea to post another proper one.

Here's the ActionScript 3 version:

function randNum( low:int, high:int ):int
{
 return Math.round( Math.random() * (high - low) ) + low;
}

And here's the ActionScript 2 version:

function randNum( low:Number, high:Number ):Number
{
 return Math.round( Math.random() * (high - low) ) + low;
}
