FF hangs when clicking Options button from All-in-One Sidebar
I'm using the All-In-One sidebar add-on. Clicking the Add-ons option in the Tools menu brings up a list of all Add-ons in a sidebar. For SessionPage, 3 buttons appear : Options, Activate (or Deactivate) and Uninstall. When I click the Options button, the focus moves from FF to what should be the SessionPage options window, but in fact nothing appears. I tried to Move the currently focused window (Alt-Spacebar, Alt-M and whatever cursor), but it doesn't work which makes me believe that the focus is simply moved from FF to nothing. Note that the Options button works properly in the SessionPage tab. I'm using FF 3.5.7, SessionPageFix 0.2.3 and All-in-One Sidebar 0.7.11. I can't conclude if it's a SP or AIO issue, but they don't work together as for the Options button of SP. Other than that, I'm very pleased with SessionPage.
