Double clicking on file and fast doubleclicing on another file cause queuing, not playing this another file. Because of queuing, not playing i click again on this second file to play it... and it is queued again, and I click, and it`s queued again, NOT PLAYED. It`s annoying, when i want to preview files! FB2K should play any file i click, not (only) queue it. So i have to w8 between clicking - it delays my music previewing...

That's because of the way windows exporer handles opening multiple files (starts new exe instance for each file), hacks with queuing files opened shortly one after another are needed for that. Please post only 0.7-specific issues in 0.7 thread, thank you.
