Are there another reports like this or counter measures to avoid

I'm not entirely sure what behavior you are expecting for a mouse
click or alt+tab in this situation (we try to support Windows, but we
don't use it).
If I understand your situation, though, the behavior you are seeing is
not surprising. There is only a single thread of execution when FiPy
is running, so being able to interact with the Viewer (change display
range, color scheme, etc.) is not possible[*] while FiPy is solving a
problem.
As to whether you can even move the Viewer window or bring it to the
front, this depends on a number of factors, but it does not surprise
me that you cannot. X windowing systems handle this pretty well.
Different viewers on Mac OS X behave differently; some can be moved
around and some cannot. With matplotlib, which you are using, it can
depend on which backend you are using. On the Mac, I have to set the
backend to "MacOSX"; there may be something you can do on Windows, but
I don't know it. See http://matplotlib.sourceforge.net/faq/installing_faq.html#backends
for a partial discussion of your options.
Perhaps some on the list who use FiPy on Windows regularly can offer
advise?
[*] Because viewing 3D models without being able to manipulate them is
essentially useless, I am working on getting the MayaVi viewer to
launch a separate process. This is not without its issues, but it
seems to work OK. We *may* try to generalize the mechanism to the
other viewers (matplotlib, etc.) but the need is much less severe and
it's not easy, so this will not be a high priority.
