I have recently "upgraded" (and I use the term loosely!) from Windows 7 to Windows 10. Concurrently, I replaced Sigma 3.12 with 3.13.
The Sigma 'User Comments' utility is a good way to keep a running explanation of design rationale on the same page as the circuit. I will admit to being a bit wordy, but never had it get me into trouble before. In a current design that wasn't even compiled and downloaded to the development board, while I was typing away suddenly my screen became framed in red with a big X from corner to corner (see attachment). From the text in the image, am I violating a text entry rule, or should I be concerned over something more far-reaching? I don't think I ever had this happen with the old system and version.
