Drag and Drop Problems

I'm trying to run Starfinder and I keep running into a problem while creating a Mechanic. I try to drag the class from the compendium to add abilities and a window pops up and shows various abilities with check boxes. The thing is, it doesn't show the whole window and I can't scroll down or anything to see if there is any confirmation buttons.

Edit: I was able to clear the window, but nothing gets added to my character sheet. Does the Starfinder content not work or something?

I don't know if the Starfinder sheet has drag and drop capability. Not all of the sheets (even the official ones) do. Do you get a box saying that the sheet is accepting drag and drop when you try to drag something onto it?

The wiki entry for the sheet [ 1 ] [ 2 ] doesn't mention drag and drop. Nor is it listed as a feature of the sheet during game creation. There was some mention of Drag and Drop when Tech Revolution was published, but I believe that's talking about dragging and dropping a ship into the game. Not sure, because I'm barely familiar with the system. That second link above has lots of helpful macros, BTW.
