Win XP SP 3

Installed latest build, re-boot.

Clicked on the icon but it never opened, received the "Please tell Microsoft about this problem."

Error Signature = "AppName: aspmon.exe    AppVer: 4.3.1.1031    ModName: aspmon.exe
ModVer: 4.3.1.1031    Offset: 0044948a"

and filename of dump is:  C:\DOCUME~1\GEORGE~1\LOCALS~1\Temp\8036_appcompat.txt

I would really like to know if my RS485 stuff is getting out on the line and I'm hoping aspmon will do the job.
