1. Thank you Ashley, I invested the issue on these forums before I posted here, and I have read that other users have successfully used global variables to identify specific points of time. My project was unable to do this, and after reproducing it in the .capx above, I believed that I had discovered a bug, since I believed others had claimed to have done precisely what I did in the past successfully. I'll seek assistance in better understanding how to have system time and global variables interact.
2. As noted in my first post, the "g" key is a shortcut for creating groups, when more than one event is selected. However, when you have notes between your events, the "g" key shortcut works sometimes, and not other times. This was a less significant bug, but something that didn't work properly, and so I thought I'd let you know. It is my belief that the .capx I provided is sufficient in demonstrating this. I thought that my explanation above would effectively explain the issue, especially when coupled with the notes of my .capx. This small bug (or not) doesn't rely on events be active, it is simply a small bug (or not) in the event editor.
Thank you again for the clarification to my first point, and I apologize for not being as clear as I thought I was with the "g" issue. I'm only trying to help.
