Just tested 2.2b40 on winUAE, classicWB lite, as described before. Loading from workbench, not early startup.
Demos work fine. Single level scan completes and demos launch with tooltypes.
Games don't finish second level scan. Quits to WB at around 2700 files. A .db files is created for the games but only goes up to midway thorugh the W folder (Winter Games!).
