Hi!
For the first issue, it doesn't happen constantly. I had it today on a dialogue belonging to that cyber thing prototype I sent you a while ago, except I didn't change any dialogue there in weeks. And oddly enough, I just opened a dozen of dialogues in Nékromegà, but no problem today for now. Maybe it happens after using the different editors for a few hours, I'm not sure.
This being said, opening many tabs led me to a third bug lol -- when opening 5 or 6 dialogues in a row, sometimes I can't close tab anymore. I have to open a new dialogue first, then close it, in order to close the other tabs.
And for the second issue, I've just sent you the script matching with the screenshot.
Anyway, these are minor problems :)
