Jan, I had only one instance checked in you settings. However, I do have the 3rd part installers from SourceForge and had run edit-multi-sessions.js he provides. This seems to have a way to bypass your single instance setting but the dll as you say cannot deal with a hidden instance. If I run his edit-single-session.js, all works in PSPad as designed. The 2 scripts he provides seems to break PSPad's design logic. To be honest it may be better for PSPad if you developed your on context dll so you could control all its operation. Regards, Pete
