Mouse over pop up no longer working

The mouse over feature has stopped working on my installation of Weather Watcher. I am using version 1.0.17 and have the latest version of Fire Fox. All other features seem to be working and I can make changes to the settings (such as number of icons to display, weather station to display etc). I have disabled the pop up blocker in Fire Fox but that makes no difference.

Which version of Firefox are you using?

Sorry, using Version 12 with Windows 7 as the OS

I’m using 12 too, but the popup is displaying as expected.

Which weather station are you using? Do you still notice this problem if you switch to a different weather station?

I have switched to every local station around my location and it still does not work.
