You can't tell the number of results
and there is a scroll bar
The number of results is clearly displayed.

Bad Example – Radio buttons are not appropriate when there
are only two options
Good Example – These yes/no questions have a better
representation with checkboxes

This progress bar looks like it is stuck at
99%. Ideally the progress bar should be
hidden when completed and replaced
by a green tick

f) Scrolling: Avoid using scrolling lists and slider bars. Difficult to
slide a finger across flat surfaces and stop it on a precise spot.
Buttons are generally easier to use than a slider for scrolling up
and down.A slider can be a good design option to help the user
move rapidly through a set of options.A slider also offers the
advantage of indicating one’s place within a scrolling list.

All popups are evil but
this may be the most
annoying one in
history.
How ironic that the
popup is informing you
that IE has blocked a
popup.
