Some notes about Combine Files

Some notes about Combine Files:

Setup:

• Acrobat is running.
• The MDI (multiple document interface) is closed (i.e. switching to Acrobat as the foremost application shows just the menubar).
• Cmd-tab switch to any application, then back to Acrobat, e.g. I am constantly switching between Acrobat and the Finder.

Combine Files:

• Go to Acrobat » File » Combine Files.
• MDI window appears with instructions to add files.
• Drag and drop some JPGs into the window.
• Thumbnails of the JPGs appear.

To the upper right, we have two buttons, Close and Combine (see attached picture).

• Close looks active but not selected.
• Combine is greyed out.
• Can't Combine, but also can't Close; neither button does anything.

Two ways out:

1. Close the "New document" tab. MDI remains. File » Combine Files and repeating the process now allows me to add the files again and actually combine them.
2. Close the whole MDI window via the close button in the title bar. File » Combine Files again. MDI opens and, lo, my JPGs are there and Combine button is highlighted and able to be pressed.
3. Or, quit and restart Acrobat allows it to work as it should always.

Also worth mentioning:

• No keybind for Combine Files, and no way to add one. 
• No way to rearrange the "Recommended tools for you" section of the MDI home window to include Combine Files so that accessing it is a one click instead of two (via menubar File » Combine Files, or, "See all tools » Combine files").
• Painful because I use this function a lot.
