Subject: [PATCH] the last patch fixed the AirportList ... and broke all other
 PUCLASS_LIST.; Unfortunately, there's no simple way to distinguish them. plib
 has no user defined widget classes, and getTypeString() -- which could be
 used for that -- isn't virtual. Sigh. I'll discuss the problem on the plib
 list. For now I can only offer an ugly workaround. (Don't look closely!)
