Ralph,
I don't know why your cross hairs won't go to 0.0, 0.0. But I do know that
LaunchCAD can only affect the way that AutoCAD performs by modifying the
DOS environment and causing AutoCAD to load AutoLISP, or other programs
that may affect ACAD's behavior. LaunchCAD is not memory resident while
AutoCAD executes. By deduction, therefore, if no other programs are being
loaded, the only possible difference can be the changes to the DOS
environment.
Strange things can occur when DOS runs out of environment memory, and
AutoCAD will also misbehave when this occurs. My advice is the same, expand
the DOS environment space with "SHELL=C:\COMMAND.COM /E:800 /P" in your
CONFIG.SYS file.
