Thanks, that is rather helpful, and the issue may have been the cause 
of real problems for some users.

There are a few other issues with caps and more recent g++ versions 
that have been standing for too long now.  Hope I can fix them in the 
near future and release a fixed version.

Thanks again, Tim
