IM clashes when used with Contact module and TinyMCE

This wierd. I use TinyMCE and it is fine everywhere else on my site. I use Contact module, and it is fine when TinyMCE is disabled or when IM is disabled. This problem only occurs when contact, TinyMCE and the IM block are all in use on the same PAGE.

It seems that the input textarea of IM grabs the TINYMCE wysiwyg editor input panel but only when looking at the contact module pages! In all other pages this does not happen. Net result, the left block sidebar expands to fill most of the page, and the contact message input area doesnt have the tinyMCE editor available. (under the contact message area there is an option to not use TinyMCE, which when selected, causes the IM block to return to normal proportions.)

take a look....

Oh yes, and it only happens when more than one registered user is on the site, as otherwise the IM block has no input textarea.

Hope all this makes sense :-)

PS. Tiny works fine sitewide everywhere else, and so does IM. I posted this under the IM module because it is the IM block that is affected, but it could equally be a bug in Contact or Tiny. I suspect its not a bug at all, but rather a clash of field definitions or something like that that causes IM to pick up the TinyMCE input area.
