The pages are written in asp.net. This problem does not occur if I simply view the page on its own. but if I add the page to a frame set.
The web page has a scolling div tag in the centre of the page. When I rollover the menu items on the left hand side this div tag resizes. This only happens if the content has cuased the div tag to show scroll bars.
does anyone have any questions as to how I can stop this from happening.
