Hi Rutah , just as i start modding you're developing the "perfect" tool for me. It tried your editor this eve. Looks great. i discovered a few issues. 1. If i doubleclick a Script in the left listbox its only opened Readonly and i cannot edit it. is this wanted. If i open the same script over the OpenMenu i can edit it. 2. If i define your editor as default-editor for scriptfiles it throws an exception when i want to edit the script from the windows-explorer. Should it open the script or isnt this function implemented yet ? Would be nice itf this would work. so it would be possible to launch the editor directly with the selected script from the Creation Kit. Also i should only raise one instance of your tool if a further script should be opened from Explorer or creation kit. So enough of annoying you with stupid requests *smile. Wish you fun and success while evolving your tool thanx till now Frank PS; I you need some help . Mention it
