Setting up Enterprise

[George C Brackett]

I have a feeling the answer to this question will be so obvious I will  
want to crawl under the rug if I get answers.  But here goes...

I have just become an Enterprise user, running Rev 3.5.0 OS X on my  
MacBook and Rev XP on Parallels, a Windows virtual machine.  What is  
the best way to work with both IDEs on the same project?  Is it best  
to have two source versions, one on each operating system, and copy  
non-OS-specific code back and forth?  Or is it better to have one  
source, written in one IDE, that's tested and tweaked as needed on the  
other?  Or is there another, even better way?

I've been compiling Windows versions from my Mac IDE for years, and  
have needed only to run the Windows standalone to discover a few  
formatting issues to be caught and corrected with if...thens in the  
single source.  I anticipate there might be more complicated issues  
ahead. ( It also turns out that ListMagic in the Windows standalone,  
when its created on the Mac, thinks it isn't registered; there may be  
other similar issues.)  I look forward to having both IDEs now, but I  
want to be efficient and effective in using them!
