noticed this during trial, and Pro paid version. after i leave laptop on overnight, in morning, after login, i have 2 windows open, but they are all blank, the title of one is Settings and one is Welcome to Mosaico. both have the logo in upper left titlebar. problem is, if i try to close settings first, it won’t always close, and then sometimes i can’t either. i don’t know why i am even seeing them. if i try to force them closed in Task manager, it froze my computer. i don’t see the black settings window anymore, either in taskbar bottom, or floating bar on desktop. running win 7, 64bit, professional ed. 8 gig memory. dual panoramic dell displays connected with displayport docking station.
