windows-keyThanks to Horst Epp, I learned that the default shortcut Windows-K used in Folders Popup to open the popup menu is now used by Windows 8/8.1 (it was available until Windows 7). In the next FP major release (v4, to be released in a few weeks probably), I will change the default shortcut key. This will not affect current user since their shortcut key is registered in the folderspopup.ini file. But for FP new installations, the default will be changed to one of the only few shortcut keys left available by Microsoft.

In order to determine what should be the new shortcut, I'd like to have Folders Popup users opinion: please, answer this SURVEY.
