Hi, Forgot bug #6: 6) When deleting symbols in math mode, subscripts and superscripts are not always correctly drawn on the screen. For example, if I type x^2y^2 and then want to change y by z, I go back with the cursor to delete y and then the second superscript "2" vanishes from the screen too, however when I type "z" instead of "y", the superscript is back. This can also lead to double superscripts or subscripts (a TeX error) which are not drawn on the screen. Best regards, ----- Serge
