Problem Entering ALT- Codes in Search Dialog

[rjbill]

In the Find and Replace text entry boxes in the Search dialog,
if I try to enter, e.g., ALT-7 for a bullet, or ALT-0151 for a Long Dash,
it doesn't work anymore.

ALSO, and I don't know if this ever worked, but, if I go up to the Greek Summa
characters drop-down in the menu when I'm at one of the Search text entry boxes,
it lets me drop down the list of characters, but, when I select one, it does not
enter that character in the text entry box.

It actually enters that character in the text file, which is a bit odd. (?)
Because it then sets the cursor back to the Search dialog box text entry.
FYI

ALSO, the Search Dialog Box doesn't have an [X} close button.
Didn't it used to have one?
