Yeah, until you actually try it.
When I do javascript projects I spend about 30% of the time getting
the app working and then the other 70% worrying about browser
compatibility and workarounds for funkiness in the browser. For
instance, if you're doing a drag-and-drop interface in Mozilla, you
don't get notification when the cursor leaves the browser window, and
mouse move events don't tell you if the buttons are down, so you can't
really 'do the right thing' in these cases. The best thing I've figured
is to extrapolate the motion of the mouse, and assume that the mouse
went out of the window if it was heading for the edge of the window and
we don't see any mouse events after a time delay.
Like GUI applications, it's easy to make an AJAX application work
80% of the time (like the GUI crapplets that come with Fedora) but
getting right behavior the rest of the time takes a big investment of
time and energy, something most open source authors, never mind
commercial entities, aren't willing to do.
