I have a user that had message manager installed and working. The IS guys did a reload and bumped her to Windows 2K from NT. I tried to load a new version of Message Manager R4.6, it loaded fine, but I get a Windows error (The instructions at 0x77fcb397 referenced memory at 0x17cc36dd. The memory could not be written. I uninstalled and reinstalled same thing. I uninstalled and installed R4.5 same thing. Anybody seen this. Of course the IS guys say its the program and I'm saying its the PC.
