My husband wants me to post this, in case it helps anyone to find the patch…

We’ve both used the Dynarch DHTML Calendar in projects over the years. And had been quietly ignoring the fact it has problems in Internet Explorer 7. The calendar displays in the wrong position when you are in Standards Compliance Mode (using a proper doctype).

Well… there’s a patch, here:

So there you go.
