Losing table colours at save

I am running Foswiki 1.1.2 from the Windows-installer.

I'm glad there is a wysiwyg-editor in Foswiki, that perfectly suits my needs.

The only thing that does not seem to work is storing the colours of a table.

So when I make a table from the wysiwy-editor and I set the background of the cell or row to a certain colour, the colour disappears at save. By pushing the button UPDATE the colour is still visible, but when saving the topic the colour is gone.

Any ideas, am I overlooking something or is it a bug?

Thanx in advance!

Kind regards,
