Has there been any progress with tori's issues - post #207?
I've similar issues with the same version of omweather on an n800 (OS 5.2010-33-1 with community SSU installed).

I think it's the applet that's broken as the application seems to work when I select from the menu but if I click on the screen applet it's buggy.

I've pretty much stopped using the app since the last release way back in April (I think?). Perhaps some issues crept in with the changes for the n900.
