I am using Sage 5.0 on a server. I use the notebook with Firefox 13.
Last Friday, I updated some code in a file from a while ago. I saved it. Today, I was looking for it and couldn't find it. The reason is, the date never got updated. It still says it was last updated 109 days ago and it's toward the bottom of the list of Active Worksheets. But, I opened it and it has the updates I made last week.
So, it's not a huge deal for me. I found it and my work is saved. But, just putting this out there in case it is a problem. Has any one else ever experienced this?
