MacBook Pro (Mid 2007), 10.4.11.

Want to remap "enter" to "option," but it's not working quite right.

It acts like it's working in the Keyboard Viewer (accessed via the "International" menu extra), but no application seems to believe it.

Here's a little test that may provide info to the developer: Looking at the Keyboard Viewer, if I hold down the Command key on either side, then press the other one and then let up on the first one, the Command key indicator remains lit up in the viewer. But if I do this with the Option key and the Enter (remapped to Option) key, the Option key indicator goes out when I release the actual Option key. In fact, after a little further experimentation, it looks like pressing ANY modifier key causes the remapped Enter-to- Option key to stop being recognized in the Keyboard Viewer.

I hope that this helps.
