No v9 properties toolbar access except in last document opened

Question

Has anyone else noticed this in v9.0 or 9.1 of acrobat?
You want to change the properties of an object such as the text format in a comment/markup text box and, even though you can select the text, "No current selection" is reported where the properties would normally appear.
This seems to only happen when the document being edited is not the last one opened by acrobat. It seems to hold true for shapes and other items that could otherwise be modified using the properties toolbar. Disabling and re-enabling the toolbar does not help. Closing the document and then re-opening it does fix the problem for the one document because now the document is the last document opened, but now the prior "last document opened" no longer works in this respect, even if it had been working.

Answer 1

Still not fixed!
Assumptions for this test:
1. Acrobat has been configured so that the "Text Box Tool" (part of the "Comment & Markup Toolbar") is visible on the toolbar.
   (Tools --> Customize Toolbars... may need to be used to se this up)
2. The "Properties Bar" is visible (a Ctrl-E should bring it up if it is not already so)
If you had to make changes to get this configuration set, close all Acrobat windows before proceeding so that the settings will be remembered and used when new windows are open.
******BUG******
Text box TEXT PROPERTIES only accessible in most recent file opened.
Steps to reproduce bug:
1. Open a 1st PDF
2. Open a 2nd different PDF
3. Arrange so both are visible.
4. in the 1st PDF create a text box and notice how the window for the 2nd PDF gets the TEXT BOX PROPERTIES BAR
5. notice how there is no way to change the text box properties in the first window.
Results: Text box properties can only be changed in the most recently opened window.
Expected results: Text box properties should work for all windows!
Note that no properties (color, fill, font, ...) of any object (line, rectangle, callout, ...) can be changed using the Properties Bar if the properties bar is not part of the last window opened.
The only kludgy workaround I've found is that if I need a working properties bar in a particular window I can:
1) save the file to capture any outstanding changes that might not have been captured (this is an optional step)
2) make a throw-away minor change to the file (I usually draw a short line segment)
3) Go to File --> Revert (& Confirm)
The file will close and reopen without the throw-away change and it will now be the last file opened so it will now have a working properties bar.
