Nope - haven't touched it.

Just logged in then and same problem occurs

Fit-To-Window' only maximises to containing User control, using IE 6 and Firefox.

In IE6, cannot apply styles using dropdown box.

In firefox 'Fit-To-Window' causes other modules to overlap with the editor.

Looks sort of like a Z-Index issue, but can't be sure.

Be sure that Terry is checking the 'Articles Module (Nested UC)' module.  I only placed the Text/HTML module there to show that it works normally in a module that doesn't use nested user controls.
