"empty" areas of some sites can't be dragged

This happens because the event target is the HTML element. That element needs to be made scrollable without including the scrollbar.

There is a workaround for this that is very easy to apply. Download the source, open content.js, and locate the following function:

  // Return the first ancestor (or the element itself) that is scrollable
  function findInnermostScrollable(e) {
+    if (e == document.documentElement)
+      return document.body
+    
    if (e == null || e == document.body || isScrollable(e)) {
      return e
    } else {
      return arguments.callee(e.parentNode)
    }
  }

Adding the lines indicated by the plus signs fixed the issue in every case I could find. To install, first disable the "official" extension, and then use the developer mode tools on the extensions screen to load an unpacked extension (point it to the directory where your modified version of the extension is).

You might also want to open the manifest and bump the version number.

Haha, I didn't even realize that you (the author) created this issue. Sorry for the explanation on how to install an unpacked extension.. :)

Thanks for the patch. I will try and apply this tomorrow at work, assuming it doesn't bring back the broken scrollbar issue.

It did bring back the scrollbar issue, but I found another solution to that.
