As you have noticed we are having issues with some of the themes. I will be talking to the developer about this problem today.
Until we can get this fixed I have swapped us to the Spectrum theme which seems to be working correctly.
If you are using a different theme and are having trouble just scroll to the bottom of a page and select Theme. Then select Spectrum as your preference. This should make the forum act as it should and run more smoothly.
Once these issues have been resolved I will make another announcement.
