Project Browser Goes Blank - How To Refresh

[Sannyasin Brahmanathaswami]

Navigator..I have it… 5.5 alpha 1?

Is that the latest?

PB: It happened midst of "group whacking" 

But more often I close stack -- its blank after that. 

I shall try for recipe…

    You could also use Navigator
    a) System
    b) What are you doing when it goes blank?  I've had it happen on a Mac when
    I'm in the midst of group whacking.
