The selection window on the databank is now the usual file selection window, so no issues there anymore, thank you very much!
the font scaling on the modpacks front page is still greyed out and it still won't let me use the beta of the modpack, only for the databank ...
If you saw the fix that you mentioned above, then you are in fact using the beta application.
The font scaling is for the application only, and has no affect in WoT itself. The reason why the options are greyed out is because:
-The modpack gets the size of your display (specifically, the height)
-Checks if the application height * scale multiplier > display height
-If true, the option (and all larger scales) are greyed out.
So, this is a feature by design. If you were trying to use the scaling to change WoT, then this should answer your question. If there's some other issue with the scaling, relating to the application size on your display, then let me know.
EDIT: in updating the version info on the server for the main channel, i see why you were having issues getting to the beta. The beta was not updated properly. That has been fixed.
