Unable to close parenthesis in pet editor

[Estecka]

Hi,

I want to create a spawn point, such that the Position X is the expression 168 - (imageW/2).

In the pet editor, I am able to write that expression up to 168 - (imageH/2, but when I try to type the closing parenthesis, the editor will refuse to write it, and instead display the menu for selecting variable names.
There is no such issue with the opening parenthesis

Copying the characters from another software into the pet editor is not an option. The workaround is to save the xml file, opening it into a text editor, and emplace the character there.

I suspect this might be an issue relating to keyboard language. I use a french AZERTY keyboard, so the parenthesis might be located on keys you are handling differently:
