I recently installed bbcsdl on my Linux Mint 19 desktop and it seems to be ok apart from a minor point ... Having opened the IDE, it initially is in a smallish window, if I click the maximise button the screen fills with the white window, but the actual ide area is only about one quarter of that. If I load a program before maximising, the ide area does then fill the screen. Is this considered normal for this version of your bbc basic?
