Bookmarklet SuperGenPass sometime fails to popup when I click the bookmark in Chrome. It does however work when on the same page works in Firefox; an example is http://www.engadget.com/login

This behaviour also replicated on a new Chrome tab (understandably, there is no domain), but some sites just fail to launch it meaning you have to go to another site, open it up, enter in [something] to get the 'Regenerate password' link, enter the domain manually then finally enter your master password to get the generated password!

Something about the makeup of the page seems to make SuperGenPass think that it isn't able/required to popup.

The FAQ doesn't make any mention of this fact, neither does a quick Google turn up anything that looks relevant.

Does anyone else have the same issue? How can it be fixed?

I'm on Windows using the current release of Chrome (5.x at the moment, but probably 18.x by the time you read this next week based on Google's seemingly logarithmic release numbering).
