Just installed v20 Beta 1 on Windows 7 x64. Good move to the Qt format help system.
One small nit: can you make the Help viewer icon in both the program window and the Windows taskbar *visibly* different from the program's familiar Slickedit icon. I tend to have the Help always open (no excuses for not learning what's already explained!), but constantly click the wrong taskbar icon or Windows-key+Number to bring it forward. (Maybe use the current Slickedit icon with a big Slickedit Blue question mark obscuring most of it).
