When a frame is hosted by a server separate from the page with the frameset tags, Watir gives Access is Denied errors.

We have some begin/rescue/end blocks in the code which appears to try to recover from these kinds of problems. This
code needs unit tests that actually trigger access is denied so that this code is tested (and therefore can be refactored
and streamlined).

With such tests in place, we could also probably improve some of our messages that appear to make the Access is Denied
issue less confusing. e.g. ie.show_frames. The wait logic also has some begin/rescue/end blocks that look like they
may have been added to handle this as well.
