- No offense meant here, but where did you hear that Win95 has

- According to _BYTE_, the only things in Win95 that do preemptive

- AmigaOS. Other than that, Win95 is still a coopertive multitasking
- system (and requires *much* more RAM and processor power to boot!).

- constraints (that I hope to soon alleviate), when I have to stop the
- Executive server. The difference in response time when starting a new
- Shell window is quite noticeable. Great program!

- Well, there are programs in UNIX that don't like their priorities
- messed with, too. Many of them simply will not let the priority be
- changed past a certain value (e.g., HP's GlancePlus software). (There
- are also some which simply choke and/or die if the priorities of
- different program tasks are screwed up--e.g., HP's "omnimver" program
- that's part of their OmnibackII backup software). However, this is
- something that a piece of software in AmigaOS, an OS in which most
- people do not intentionally change task priorities, and the OS does
- not normally make provisions for doing it automatically, is not likely
- to pay attention to. Perhaps they should?
