Since the two last versions (3.6.5 Beta and the current 3.6.6), the shortcuts in the menus are not displayed correctly. For example, I see, in the "Files" menu:
"Edit (alternative) Clipboard does not support IconF4"
"Add/Edit Link... Text exceeds memo capacityF6"
Or, in the "Mark" menu:
"Select/Unselect Unable to insert a line"
"Select All Cannot open clipboardA"
This is very strange. I'm on a WinXP Pro, in French; and I can say that this bug wasn't there in version 3.6.1
Hope you'll succeed in fixing that.
