This is a strange problem - I can't open my 'preferences' menu. Everything else seems to work, but when I go to [tools]-[preferences], I get a half timer/half arrow mouse cursor, and it does nothing.
All other functionality continues as usual (I can run programs, close the emulator, etc) but I cannot open the preferences menu for the life of me.

I have tried uninstalling and reinstalling. I had other versions of Symbian before (6.1, 7.x, UiQ 2.1, etc) but I have now removed them all with the same result.

Any ideas?
