Paragraphs underneath a table corrupted...

Just in case anyone else has the misfortune to encounter this one...

Today the indent on pargraphs under a table I added suddenly had a greater indent for no obvious reason. Checked settings and HTML view no joy. Also re-applied style, tried formattiung as none and then re-applying. Also list of styles on drop down in toolbar dissapeared...

I removed the table and was then able to stabilise the offending paras. The table contained merged cells in the second column of two and would seem to have been the culprit.

Anyone else come across this one?
