fixed a bug in the haplotype groups

Fixed a bug that was causing the haplotype data in the pop_hap array to sort incorrectly. Basically there was an extra for loop in there that was causing the pop_hap array to be jumbled an extra X times. We're now up to version 2.3.1.

missing table in IE

Help! I can't figure out why this table won't show up in Internet Explorer (v. 7, in Windows). The table (id="popsizelegendtable") is viewable in Firefox but totally disappears in IE. I have no idea what's going on. Here's the unprocessed source. Is it a CSS style issue? Or is some of my javascript overwriting some styles? The nodes and data are still there in the HTML tree, but it just isn't viewable. I feel like I've turned every display to block and zoom to 1 and am out of ideas.

Works in Firefox and IE (almost)

Version 2.3 is now up! Now it works in Firefox on Windows, Linux, and Mac, and has almost all functionality in IE in Windows and Mac. The only thing missing it not being able to draw the sample size legend in IE.

Aha! Getting google to return svg's instead of img's solved

So thanks to Mike William's post to the Google Maps API Google Group, I can get GPolygon to return svg's instead of img's in Firefox in Linux. Yay!

Basically, you have to set these two parameters, _mSvgEnabled and _mSvgForced to true in order to force Google to return SVG's. Here's the code snippet that made everything better:

function load() {
if (GBrowserIsCompatible()) {
// Initialize
_mSvgEnabled = true;
_mSvgForced = true;

VML - link to reference

Conflicts between jQuery and Prototype objects in IE

I'm not sure that I have this problem correctly diagnosed, but I've been noticing a lot of errors in IE when I have lines of code that combine jQuery objects with Prototype functions. I guess this means that I've been sloppy with my JS and Firefox has been letting me get away with it! Here's an example of code that works in Firefox, but not IE:

var block = jQuery(".widgetBody", $(elementid))[0];
var blockstatus = block.getStyle('display');

It seems like the problem is mixing the jQuery object, block, with the prototype function, getStyle(). The error is removed when I replace the second line with a call to a jQuery function instead:

var blockstatus = jQuery(block).css("display");

I guess it makes sense that combining jQuery and Prototype code is a bad idea. I was using Prototype to begin with then started using more and more jQuery, and never went back to clean out all the Prototype. Heck there's even Prototype in the line with the jQuery search! Anyways...laziness is costing me now.

Addition of VML line critical to getting things working in IE

I can't believe I missed this until now. To get the polylines and, thus, polygons to render correctly in IE, you have to include a reference to the vml namespace. The top of your document should look like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="" xmlns:v="urn:schemas-microsoft-com:vml">

See the documentation on XHTML for slightly more info.
