maybe iam using it wrong, but might it be that Dialog(Open File) is not working properly?
Right now Dialog(Open File) is only capable of opening Directories…
And when clicking abort VVVVs Gui is freezing, what can be solved by Middleclick.
something wrong for only you I think d0t. Working in 45beta31.2 for me and used in other projects while back - file selecting no problem. No GUI freeze either.
