I always thought system 5 felt very flaky. Jus the way the orange bar moves in the Finder when copying files should leave you to believe sys 5.0 is flaky... :-) Seriously, I have felt for a while that the basic features of GS/OS seemed flaky under system disk 5.0--from install to copying files. Not only did the icons change, but many other things that felt like "home" changed, making me feel that doing ordinary things under GS/OS was no longer quite right. In fact, some software that demands Sys software v5.0 doesn't work under 1 drive...though everything indicates that it should (this software should pop to mind to a few readers here). I feel that it is the new system which is messing up...An inexplicable feeling for sure. GS/OS 1.0 (on sys disk 4.0) seemed solid, in fact I still use it as my default secondary operating system (I boot into ProDOS 8 always, and keep GSOS as a file in my root directory to boot from as a secondary). Sys disk 5.0 doesn't give me such an easy time booting (sometimes it does, usually it doesn't). Other than the obvious Quickdraw routines and forked files extensions, what else has changed in v5.0.2? Why does the Finder, when copying files, not seem to increment to copy bar properly? Why does the SCSI driver there seem to have this new bug in it? What exactly has happened to Apple's high standard of quality control? [I ask anyone to name an actual *BUG* in Applesoft, other than the ONERR cannot-have-another-statement-on-the-same-line quirk? Applesoft is amazingly stable for v1.0...in fact, Apple users have come to expect that from Apple, so anything less, (ie., other-computerish) seems a let down. I'm just trying to put my gripes in perspective...on an IBM compatible, I'm happy if the disk drive doesn't munch my disks, let alone read them in correctly. :-)] Kent Dickey [This post also comes from a recent purchaser (but not yet recipient) of a 65 Meg SCSI hard drive, who doesn't want to hear about the latest system software bug in SCSI drive software.....] kadickey@phoenix.Princeton.EDU
