X-Notifier 3.5.6 preventing login window from popping up

When I have X-Notifier enabled, the LOGIN button on the site: http://www.ingdirect.com.au/ does not work - nothing happens and no error or other message is displayed, it's just non-responsive.  If I DISABLE X-Notifier 3.5.6 the button works properly.
I have several other add-ons and to isolate the problem I disabled every single one except x-notifier and i can confirm that even with x-notifier as the only enabled add-on, the button fails.  Disable it and the button works.
Any idea why this is happening - what interaction is going on between x-notifier and other web page elements like these buttons?I can't know for sure when this may have started since I don't visit that site frequently.

I'm running Firefox 36.0.4 and just updated to X-Notifier 3.5.6   

...so I went to www.ingdirect.com.au and looked at the Login button.

When I move my cursor over that button, it changes color from dark blue to a lighter blue... and when I click that button... I get a pop-up window with the 'Log into Online Banking' screen.

Perhaps your update to 3.5.6 did not properly install... I would try (exporting your x-notifier accounts, and) uninstalling X-Notifier and re-installing it. (import your accounts)

Otherwise, I've only seen non-performance of webpage items when my tracking blockers have interfered... like AdBlock Plus or Disconnect, or javascript blockers, popup blockers, etc.

That worked! ... I exported - uninstalled - reinstalled - imported and tried the site again and it worked.  Seems odd that that was the only site where I had an issue and I don't understand why it would have any effect at all on any page elements.  Anyway - it seems to have fixed itself after the reinstall so thank you for that.
