You are probably right, it is not a perl problem. The actual issue is a null pointer bug in mshtml.dll at offset 000cc4b4. It is reported here M$ Bug Report The suggested resolution is to update IE.

This obviously does not solve your issue but it is unlikely to be simple. For example if I go to your page directly I will crash IE (most but not all of the time of course!). However if I save the page out of Firefox it never gives an issue and following the High Res link works to boot.

You are basically exercising almost all features of IE with JS, CSS and ActiveX for the Flash. If you have a look at what this DLL actually contains you will see:

The error offset I get is between the DllGetClassObject and the DllCanUnloadNow entry points so is rather unhelpful as it does not point to an obvious cause like a function called RandomCrash(;-).

It is probably a parsing error of some description. I suggest you run HTML Tidy over the output and correct any major defects it finds in the HTML. This may well fix the error. For example on line 17 you have <a></a> which might choke a parser that was not ready for it. Also on line 23 where you have a lot of JS calls you use all sorts of variable syntax. May be no issue but I am vaguely supicious of the JS due to RunHTMLApplication function in the errant DLL. If not good luck.
