I'm using the PRO version and just had my client email me that the work I did doesn't render properly in their version of Word (2003). It seems fine in a more current version. When I investigated other office programs (LIbre, Openoffice) I found different results in each version ... the most concerning being that sometimes my $VARIABLES$ aren't written at all.
I'm not even sure what I could do it help backwards compatibility issues. Any advice?
