Richard Fillon has sent us an email to tell us that the game works well with Mac OS X Lion latest update! Thanks for this good news :)
Release of Mahjong In Poculis 4.31. The main changes come from new asian layout names and the in-game publication of best score and best time.
We are writing the game into another language to make it compatible with new Mac OS X versions and tablets!
Earlier this year, when we add 180 more layouts to the game, we introduced a subtle bug which removed the functionality to publish a part of your Expert scores. Today it works again thanks to Madeleine from Canada who reported the bug this morning.
Release of Mahjong In Poculis 4.2!

You asked for a special feature for registered users. Here it is: starting from Mahjong In Poculis 4.2, registered users can play all the layouts using their favorite theme!
Note for Mac users: recent versions of Java for the Mac plateform occasionaly make the game to crash. Don't be scared by the glitching screen, it won't have any consequence on your computer. We are going to investigate for a solution for the following days.

Windows plateform owners don't have any problem because Java is embedded in the package they download. When there are troubles on Windows, they always come from outdated graphic drivers. Just update them to make the game run correctly and fast.

Update March 17, 2011: An fix has been found! We removed the loading screen code that was here for a long time and it seems to work again!
