iframe scrollbar issue

i can only find three options for scrollbars: yes,no,auto
the issue is this... mozilla is doing what i want (i know netscape does this too since i've seen it in netscape 7) which can be seen here:

yet ie does it radically differnt. there's nothing that should be causing any horizontal scrollbar, yet.....

note: there might be a difference on one of the three iframes havng information, but that's more because i removed the closer and just closed it out since it's oalways a sub page. when someoen has information there it'll still have that quirk.

right now the iframes are set to "auto"
i want the scrollbar that's vertical when needed, but iit's adding an ugly horizontal one in ie. is there any way to remove it? i haven't tried setting the scrollbars to "vertical" becasue i can't find anything saying that would be supported.

the profile in that screenshot is....

css is:

Quote: /* body */
body { background-color:#000000; color:#ffffff; text-align:center; font-family:Arial,Courier; }
body.rebod { margin:auto; }
body.subpage { margin:0; padding:0; overflow-x:hidden; width:100%; } /* for iframes */

i know that M$IE puts the scrollbar outside of the iframe... is it possible to set the width to 100%-20px (approx size of the scrollbar) or do i need to use multiple classes, one for each page
