How to configure my favorite editor in Quartus?

Altera Quartus, as most other EDA tools, allows users to use their favorite editor, instead of the built-in editors. For Quartus, this feature can be activated in Tools > Options > Preferred Text Editor.

When I fill in stuff in this dialog, Quartus does not store the data. The old editor is still used, and when I come back to the dialog, the default value is still there ("Quartus II Text Editor" is selected).

Have any of you encountered this? What am I doing wrong?

• Does anyone know where Quartus stores these settings? (there might be a problem with permissions?) – Philippe Jul 19 '11 at 13:47

It turns out that things are stored in \${HOME}/.altera.quartus/. This directory was owned by root on my system, probably because I had executed quartus with root privileges before.
