When having an IFrame inside SharePoint 2010, scrollbars disappears under some cirumstances depending on window size and mouse position. If holding the mouse over the address bar while refreshing the page; All HTML content dissapears from the internet explorer window. The content appears again when moving the mouse slightly. The iframe also does not respond to attributes set on the html element. For example setting the scrolling attribute to srolling="yes" should always show scrollbar, but this has no effect. This occurs on both IE9/IE8 XP/Win7. We are doing some resizing of the iframe using JS based on the users screen resolution, this worked fine for SP2007. Anyone know of any known gotchas here?
My problem looks very similar to the one described here: https://sharepoint.stackexchange.com/questions/11149/show-on-iframe-div-with-jquery-ui-causes-iframe-sharepoint-page-load-to-fail
