Hello Richard, I discovered a recent UAE freezing problem in OS4update1. It's exactly the same problems I had with Catweasel. Well, the Cat isn't here any more and UAE will freeze on all versions. I even installed the OS4pre version and it fails. One of the 'big' changes in IO for OS4update1 was the elimination of of CIA-resources.library.kmod in Kickstart. Does it effect E-UAE.? I have to say yes! The freeze: I loaded both OS2 and OS3 to any version of UAE and freeze like this: From WB, I use shell to list the floopy. Quit shell. Load another floppy. But now, in the shell, the keyboard, is lost. "list" won't type. If you touch the mouse--freeze! Mouse, keyboard, floppy are all connected to a Complex Interface Adapter in the real Amiga IIRC. Ah yes, 'Gary' was a cia controller. Sorry I went and wrecked the enviroment, but I am recyclabel! :) Regards, Dennis
