[Pharo-project] Pharo windows unresponsive while busy?

I think, there are still some serious problems hidden (design problem?) downunder, which have to be solved ... regards, Guido Stepken packages := PackageOrganizer default packages select: [ :each | #('Collections' 'Kernel') includes: each packageName ]. browserEnvironment := SelectorEnvironment new label: 'Seaside Methods'. packages do: [ :package | package methods do: [ :method | browserEnvironment addClass: method actualClass selector: method methodSymbol ] ]. browserEnvironment open
