Next time it happens, could you submit a bug report from the Help menu and
check the 'include error log' checkbox?  This might include some clues as
to what's going on.

After you do that, try removing the 'cache' directory inside your
~/.wingide2 directory, and restart Wing, to rule out any odd analysis
state.  It is most likely the analysis engine going into a loop, so could
also be caused by the particular content of your files.  Most likely
something that changed recently before you started seeing the problem.

The next beta, due out in a day or two, goes further to fix this by 
limiting time allocated to recursive analysis.  However, we're still
interested in finding and fixing analysis recursion bugs so if you
have any hunches what code is causing it, please let us know.

Thanks for the report.
