-* Fix occasional glitch when scrolling text in Oracle interface. See [[media:Oracle-glitch.png|this series of screenshots]] from the DIRECTIVE CHARTER article. (It happens in other places as well.) This is actually not a bug in the Simon engine, but rather a problem with the automatic calculation of dirty rects that we use to speed up full screen updates in some engines. Maybe the checksum algorithm is more likely to fail when there are only two colours involved?

-* Currently, it is difficult to extract the Feeble Files .cab files for people on non-windows systems. Sadly, unshield [https://sourceforge.net/tracker/?func=detail&atid=399601&aid=1429549&group_id=30550 does not properly support the FF .cab files]. It would be nice if somebody could work on this. Maybe looking at the [http://programmerstools.org/node/122 i5comp source code] could help.
-UPDATE: Actually, applying the following patch to unshield allows one to use "unshield -O x data1.cab" to extract the FF data1.cab file.
