I searched but didn't find anything relevant, except for a few posts of others with the same problem.

I cannot seem to open the properties for the scripts on the stages tab. I create a new log and it allows the properties button to be selected, but clicking it does nothing.

On other quests I created it works fine, but at least two of my quests I cannot access the properties.. If I change the kmyQuest dropdown to NONE or to my quest name, it still doesn't fix the properties opening.

Is there something obvious I'm missing?

Anybody experience this?

Go to the scripts tab in the quest window and select the properties there. Does it work? If not, remove the script. Then write something in the papyrus fragment in the quest stage and see if it works then.
Haven't experienced it yet, though I only have one quest atm, maybe I'll have that bug later, too.

The properties button works fine on the scripts tab. No problems there. After making a script and saving it, I go back to the stages tab and still no properties menu pops up.
