In non-latin strings, typed chars appear not in cursor position

[aminco]

Under Win 7, Maindmap tab allows the use of mixed English and Hebrew as expected. A joy to use!
However, when placing the cursor on a line with Hebrew in it, and starting to type, the first character appears not in the cursor's location but on another location.
For example, placing the cursor between א and ב in אבגדהוזחטי and typing 1 results in
אבגדהוזח1טי
In general, the position of the typed char seems to be at the other end of the string + 1.
