No.03634 etabeta Developer Jan 23, 2009, 22:45	the probable culprit is in video/taitosj.c. the driver has been updated to the new graphics element handling and probably either some element is marked as dirty when it should not, or it is using the wrong element from characterram... however, no evident problem is present in the u1 update, so further investigations are needed (I cannot compile right now...)
