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.

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

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:

Internet Explorer -- pain in the ass
I've started debugging the program in Internet Explorer (v. 7.0.5730.11) on a Windows machine. I've been using Firebug Lite and the IE developer toolbar to help debug. Even put together, neither of these is remotely useful compared to the awesomeness of Firebug in Firefox. Anyone out there have a recommendation for anything better for IE development and debugging?
XRay is another interesting CSS viewer tool that works in any browser.
