Problems on all platforms

- All editing operations are restricted to cells whose coordinates are within +/- 1 billion.

Windows problems

- None.

Mac problems

- Dragging the sash (the thin vertical bar separating the file panel and the viewport) can result in ugly flashing.

Linux problems

- Scroll bars are not updated correctly while resizing the window.
- Golly has serious problems with Ubuntu's Unity interface. For example, selecting a modal dialog like Control > Set Rule can freeze Golly. Most (all?) of the problems can be avoided by disabling the global menu bar. For more details, see this forum post.
