Also, once something breaks, other things will quite likely break, so don't worry about the tags, and make sure that every time you try to reproduce this you've restarted Firefox immediately before.

Security software - how do I check on this? I'm on a 2013 Macbook, running OS X 10.8.5.

No, the relevant action is selecting a note item in the middle pane, not trying to click on the right-hand pane. Open Zotero, scroll to a note but don't click on it, enable debug output logging, click the note item in the middle pane so that you see the problem, submit.

I tried to follow your instructions, hope I did that correctly.

(Though attachments have notes as well. Is that what you're referring to, or does this happen for regular notes as well?)

Hi Dan,

I'll try to clearly describe what is going on.

Far left column - folders, with tags below that area, then a search window/box right at the bottom.

Middle column - reads "Title" at the top, then has the files I'm put into folders/uploaded, which I can still click on. When I click on one...it opens up info. in the third, far right column.

Far right column - shows the file name at the top, then filename, modified, indexed, related, tags. Below that is an area where I've been writing notes. Essentially a Word doc. area, I think.

I have been taking notes in this box/area. However, starting yesterday morning...when I click on a file in the middle column, this "notes" area is blank. And, I can't add anything new to it...it's essentially dead or blocked.

I don't know what changed, I don't know how to see all those notes I took.

Sorry for the confusion. I wish I was better at sorting this out myself, but I'm not sure what is going on.

Hello,

I'm not positive. How can I tell the difference?

I will say that these are all files, PDFs, images, etc. that I have personally collected. They're all saved on my hard drive (and backed up on an external HD), but I'm using Zotero to organize them and tag them for the purpose of grouping them to then write about them.

Okay, then I'm pretty certain these are all in "My Library."

I have not/am not sharing this with anyone and these are all journal articles, PDFs, digital images of files, etc. that I have collected myself.

Based on the image you linked and in looking at what I have in my Zotero window...the items are in "My Library. (no group library.)

Yes, I added a new item view the + button in the tool bar.

However, I can add Tags...but the notes section is still un-clickable. Can't put the cursor there, can't add any text in there.

Sure, here you go:

Any chance that the font is just white? Can you click on one of the note fields, type some letters (even if you can't see it) and then press Ctrl/Cmd + A? Does that highlight anything?

Also, could you turn on the notes column in the center pane? At the top right corner of the center pane there's a button that you can click to show/hide columns. Show the "Notes" column and see if it indicates any notes for items that you expect to have notes.

Click on the "HTML" button. Copy paste the contents here for one of the (shorter) notes. Make sure you select "Text" before posting.

Is this what you are after? I clicked HTML in the notes section, then it opened a separate window, I copied and pasted that below, with "text" clicked down below.

Yes, if I click on the Notes section, which appear blank, but do a "select all" then paste that into a Word doc, yes, the Notes that I'd like to see do appear.

I can't see it in Zotero, but it is there, and can be copied/seen in a Word doc.

Bit of a long shot, but try reinstalling Zotero Standalone.
