Cannot dismiss "Find and Replace" bubble without using mouse
I have been a NoteTab user for many, many years, approximately from the beginning of the product. Lately, whenever I reinstall it, I get weird behavior that I never saw before. I'm sure there must be a setting for this, but I have not found it.
When a do a Find and Replace, selecting the "Replace All" option (by typing the Ctrl-A key combination), the Find and Replace bubble in the following picture appears. I used to be able to dismiss it by simply pressing the Esc key. Now, I have to take the time to move my hand to the mouse, move the mouse to either the bubble or the Close button, and press the mouse button. How can I get back to simply pressing the Esc key?
