Not a very large or important bug, but I noticed that the scroll-bar for browsing ships (Purchasing at a station, but everywhere?) disappears when there are not enough ships in inventory to need to scroll down. This would be fine except that I scrolled down, purchased the only ship on the 3rd row, and was stuck unable to scroll up and see the top row. Easily solved by switching to another dialog screen and back, but not a smooth GUI experience.
This was with Uumoz's Sector Journey 1.0 and Lazy Lib 1.6 mods active.
