I typically tag my new resources in the info pane in the Library window. I almost always assign several tags for each resource. It used to be, I would press the enter key to finish one tag, and the cursor would stay in the Tag box, so I could immediately begin typing my next tag.
With Logos 9, I notice that aftering entering a tag, the cursor stays for just a moment in the Tag box and then jumps up to the "find resource" search box at the top of the window. This means I have to click the Tag box multiple times to enter multiple tags. This is an undesirable behavior for me.
