margintext drifting down the page

[Duncan Hothersall <dh@capdm.com>]

Hello all.

I have an odd behaviour which I think I just about understand but can't fix.

I use \margintext{Note that ...} to place little notes into the margin 
next to things in the running text. It has worked beautifully for all my 
content up till now, but I now find myself wanting to put a note next to 
a \bTABLE...\eTABLE and the margin text now drifts down so that it is 
beside the content that follows the table, rather than next to the table 
itself.

So,

\margintext{This works well}
Normal running text takes a margintext without problems...

but

\margintext{This drifts down below the table}
\bTABLE
\bTR ...
...
\eTABLE
The margintext appears next to this normal running text...

I'm using the latest stable release.

I'd be happy with a workaround that enables me to have this appearance. 
I have tried putting a \strut in front of the table but this only shifts 
the margintext up a little bit. Is there something else I can do? (I 
tried wrapping the table in a \vtop, and in an \hbox, and in an 
invisible \frame, but no luck.)

Thanks for any help.
