Hi, Walt:

Notation Composer is a very "benign" program, in that it doesn't make any deep hooks into the system or play around with graphics settings, sound settings, etc.

While no software is completely bug-free, I can't recall a single system-crashing fault from any public version of Notation Software's programs, and I've been using them since the very first betas of version 1.

You can install with confidence.

Good luck.

David
