Luma 1.4 has a UI bug that appears after you have opened your first popup window. Even though you close the window no further windows will open until you quit the program and start it back up. Once it is back up again you will be able to use one popup window again. Rinse wash and repeat... This pretty much kills this programs useablility. The author has been informed and has responded with a test version which works normally. For more ifnormation see this bug on sourceforge: https://sourceforge.net/tracker/?func=detail&atid=589029&aid=1039138&group_id=89105 This is mainly a FYI for the package maintainer hopefully upstream will have a new release shortly until then this package should probably remain masked.
