Hi Alejandro,
Regarding dialog width, according to Juan there are technical issues that now prevent correct layout of variable width section bars. It may be we can make the default width wider to help mitigate the problem. I will investigate.
Regarding description editing from the arrow, I do not understand this comment, please say more. The expression editing dialogs do have a "fat blinking cursor" problem in 1065 Win7.
Thanks,
Mike
