Warning: This webpage testcase creates severe problems to Internet Explorer 7. Make sure you have the Windows Task Manager opened so that you can monitor the CPU percentage activity for applications.

Main content in this CSS columnar layout goes in here

Warning: Make sure you have the Windows Task Manager opened (right-click on the task bar and select Task Manager) so that you can monitor the CPU percentage activity for applications.

Steps to reproduce:

- Load this page.

- Load this page and then do a left click in the middle of the page: then, the content of the whole webpage disappears!

- Load this page and then try to select some text with the mouse or with the keyboard: task impossible to accomplish.

- Scroll down the page, then increase (or decrease) text size with View/Text Size/

Actual results in Internet Explorer 7:
The iexplore.exe application CPU percentage activity will be in the high 90%s and will remain in the high 90%s. Increasing or decreasing text size (View/Text Size/) will also create an hung application with unpredictable page layout. Trying to select text with mouse or keyboard will be impossible to accomplish.

To disable, to disactivate the hang bug, just scroll down this page with mouse (clicling the vertical scrollbar down thumb) or keyboard (PgDn, arrow down, End). Then a background-orange right sidebar will become visible, viewable when you scroll down a bit and then the CPU percentage activity for iexplorer.exe will go from high 90% to 0%.

Valid HTML 4.01! Valid CSS!

This orange sidebar will become visible, viewable when and only if you scroll down the document box a bit. And when you scroll down the document box, the CPU percentage activity for iexplore.exe will also go from very high (in the high nineties 90%) to 0%. So, this is a very nasty, severe layout bug occuring in this page.

"I'd also like to turn comments like 'IE 6 and IE 7 failed to render even basic columnar layouts in CSS' in to solid work items, but I don't understand the problem - much of the web uses columnar layouts that work in IE." - Chris Wilson, August 10th 2006
