Strange, we've only ever had it happen on Retina/4K/5K etc. It currently affects my M1 Macbook so it's not a non M1 thing.

Try this - disconnect the 4k screen, then go to your user Library/Preferences folder and delete the com.pgmusic.Band-in-a-Box.plist file from there. Then go to your Band-in-a-Box folder and rename the Preferences folder to something else (for backup), then run BIAB. It should act like it's on a new computer - see if the save/open dialogs are huge again.

After trying this, you can delete the new Preferences folder and rename the old one back. The deleted plist file doesn't need to be restored.
