Content longer than iFrame when scrolling turned off

Hi, we've been trying to sort out this issue but can't seem to figure out what's causing it.

We have moodle being displayed in an iFrame within a Joomla page. When the length of the content exceeds certain value, the iFrame cuts off the bottom portion of the content. This happens whichever Moodle theme we use. One workaround is to turn on scrolling, however this will results in 2 scrollbars (ie iframe scrollbar, and browser scrollbar).

Is this a known issue and is there a way to fix this?

Thanks.

Hi.

Are you using auto height in wrapper?

Yes auto-height is turned on.

Edit: Hm, scratch that, it's showing fine now. Not quite sure what was wrong then, will update if it occurs again.
