When you double click on questnames / questid's etc. it will open the popup box.

Currently it opens regardless of whether or not you click the same item. So if you click on two different items within a short timeframe (1,5 sec?) you will end up opening the popup window for the 2nd one.
Suggestion: Check if the same item is selected twice. If it is a different one - don't open the popup box.

gotcha. fixed. ty for reporting.

Can you maybe add a screenshot to describe the problem?

If you click once at 1(QT4402), 2(QT789), 3(QT794) it will open

Even though you didn't double click 2(QT789).
