.fmp12 Extension can break your scripts
If you have script steps or calculations that use & ".fp7" you will experience script errors in the old version after converting to Filemaker 12. I encountered an error message during my backup script which led to this post. I've posted a solution on my blog.
In yesterdays post I advised caution in the use of a converted file (.fp7 to .fmp12) and today my own files verified my post.
