Can't drag/drop "People" into "Group" in Photoshop Elements Organizer

I have never seen your issue reported before.  So, when all else fails, my motto is delete the preferences files.  That puts the program in its out-of-the-box condition. You don't need to do anything to replace the preferences.  They are rebuilt automatically.

Hmmm . . . . .  Is this a problem that has only just started?  If so, try resetting the preferences file. Immediately after launching the Organizer, press Alt+Shift+Ctrl. A message should pop up asking if you want to delete the Settings file. Answer OK.  (Don't have any other programs open when you do this as the message window sometimes gets lost behind another window.)

How large is your catalog?  How many Named and UnNamed People stacks do you currently have.  (The number can be found in the lower left of the status bar.)

Also, what are the specifications of your computer - CPU and amount of RAM?  I have a very fast computer and I rarely use People Groups.  When I tested it out to help you, I found that it was very slow to respond when filtering by names of groups.

I shall await your further response before offering some other trouble-shooting suggestions.

What OS and version of Elements are you using? 

I assume you are talking about the People room. But are you talking about the Named or the UnNamed People tab? In other words, have you already applied a name to the person in each of the stacks?  Or are you just trying to group the UnNamed People stacks by Group Name?  And are you talking about dragging multiple stacks of different people or a stack of multiple image faces?

If you are in the Named People tab, when you drag one or more stacks to the Family name in the Groups panel, you are not going to see anything happen.  It is only when you try to filter by the group that things will change.  So, initially, the Groups panel will show All People highlighted and the label over the stacks will say All People.  But if you click and highlight Family in the Groups panel, the label over the stacks grid will change to Family and only the stacks that you have grouped as Family will appear in the grid.

If you are in the UnNamed People tab, you can drag stacks to a Group in the panel.  But the stacks that you have so grouped will only be filtered in the UnNamed People tab and will not appear with stacks of People that you have named (which appear in the Named People tab).

When you drag a keyword tag to a photo, here's what should happen (in Windows):

• Click on the keyword tag and make sure it is highlighted
• Left-mouse click on the highlighted tag.  The cursor should change to a hand.
• As you start to move the mouse, the cursor will change to a red circle with a diagonal stripe through it (indicating that the mouse is not over an image to be tagged.
• As you hover over the image(s) you wish to tag, the cursor will change to a + sign.
• Release the mouse and the tag should be applied.

If everything is successful, a tag icon will appear in the Details view of the grid.

Try performing each of these actions slowly.  Sometimes if you rush, the program can't catch up with you.

You can also click and drag an image to a keyword tag.

Finally, there is no paid upgrade that you need to worry about to get full functionality of the program.

Continuing beyond the People-to-Groups problem, I find that nothing happens when I try to drag a keyword tag to a photo.
