There has been a change in Trac behavior recently in my install and I didn't change any configuration that I'm aware of. It just showed tonight and wasn't there a few weeks ago.
When you open an existing ticket, the "modify ticket" and attachments sections are closed. I have to click on the ">" button. Previously, these sections were open whenever opening existing tickets.
Yes, there is a work around but when I go to a ticket, I'm almost always interested in these sections. I'm running Trac version 1.6. So any changes as of late?
