problem editing categories

I have 11 categories so far and when I tried to save them after assigning positions I got a strange error:

ErrorCompany ID is required (the company_id param)

Even after closing the page and going to the categories page again the error persisted. Does this indicate corruption n the database? How can this be rectified?

Thanks for any insights.

It's caused by a bug (of sorts, actually a spelling mistake) - the fix can be found here.

Thanks! My install wants to upgrade so we'll see if that will fix it.
