Kipp, it doesn't crash on NT

The demo crashes in an assertion in the block frame code (and its a valid assertion); a simple tweak to the test so that it invokes the setTimeout call during the pages onload handler causes the crash to go away. So its a race condition between the timeout and when reflow gets around to creating the frames...What happens is that the left attribute is changed by the DOM and this should be triggering a rendering operation; instead its triggering a "reframe" because the primary frame has not yet been created (primaryFrame in nsCSSFrameConstructor::AttributeChanged is NULL). Vidur - you should take a look at this and figure out how this class of problems should be handled. Thanks.

This is working for me, Linux rh5.2. marking WORKSFORME.

With the latest Linux build (5/17/99), I can load Demo #13 without it crashing.
