This section lists all known bugs and limitations. If you come across any problems not mentioned below then please report them to Andrew Trevorrow (andrew@trevorrow.com) or Tom Rokicki (rokicki@gmail.com).

Problems on all platforms

- Golly is a work in progress and we hope to add more features, including support for toroidal universes, non-rectangular selections and more sophisticated editing capabilities.
- All editing operations are restricted to cells whose coordinates are within +/- 1 billion. There is also a bug in the HashLife algorithm that prevents you from editing any cell states if the pattern is very large (outside the +/- 1 billion limits).
- The QuickLife algorithm has a minor bug that can cause selecting a large pattern to appear to be incorrect. The selection is actually correct but the rectangle is slightly offset (by one pixel).
- Pattern rendering needs to be optimized, especially in the Mac and Linux apps.

Mac OS X problems

- None.

Windows problems

- None.

Linux/GTK problems

- None.

Linux/X11 problems

- The Linux/X11 app is no longer supported (the source code doesn't compile due to limitations in wxX11). Linux users will have to run the GTK version of Golly.
