Category Editing Problem

[Lionel]

There seems to be a bug.

I have category 1 as a top catego
then category 2 as a child of category 1
then category 3 as a child of catego 2

then I try to edit and make category 2 a child of category 3 instead, on submit, in Firefox the php tries to download and that messes all categories preventing a lot of them to display.

I had to manually revert with phpadmin.

Trying to make cat2 a child of cat3 would have left cat2 without a valid parent category, so I can see why that would create problems. Guess I need to see about adding a check to make sure someone doesn't try to do that.
