Special Characters window does not remember user resize
Nightly d08e14c (4 Jan 2016) on Win 7 HP
If you open the "Special Characters" window (F2 in text edit mode) and resize it, the new size is only remembered for the same session. When you next open the program the custom resize is lost and the window returns to its default size.
This is a problem with at least two other windows. See also:
