Concise problem statement: Clicking "Special Characters..." in the Edit menu does nothing at the time of click, but now the "Characters" dialog, with nothing in it, will not go away!
Steps to reproduce problem:
1.Open Adobe Reader
2.Click "Edit"
3.Click "Special Characters..."
Results: Nothing at the time, but every time I click in any other application, and even in Reader, the "Characters" dialog pops up briefly, with no close button and nothing in it but a title, and disappears again. Then I have to wait a second for my cursor to appear in the application I was trying to access. If I click away from this text box, it will come up. If I click back in the text box, it will come up and I have to wait for the cursor before I can start typing. I have closed Adobe Reader, but the dialog still pops up. Shut down and restarted, but it still shows up. Uninstalled Reader and restarted, reinstalled Reader and restarted, opened and closed Reader and restarted, even tried to click to same menu item in the hopes that something I could DEAL with would open, and restarted AGAIN. Still the dialog pops up even when I have just restarted and haven't opened Reader. Reader is not in my "Start Up" apps.
I cannot use my computer with this dialog interrupting every action!
