Unfortunately the print screen still produces garbage but you can capture using the screenshot button still (which may be a bit rough if you don't have multiple monitors). However I may be able to capture the print screen before PSO processes it and do a manual capture instead (such as the capture done with the screenshot button in the launcher).
You sir, gave me some work to do (again)!
At least right now it doesn't crash when regain focus and has it's own taskbar window (with icon) if you do Alt+Tab to something else.
Off Topic: As you may know (or not) I'm now managing Palmacosta along with Didi and we accomplished so much in the past weeks. I wanted to ask if you'd be ok that we make your quests available in Palmacosta, if so, please send me a PM and we'll take it from there.
