I have a workstation setup for Accpac 6.0. There are customized operations done in VB Macros.There is a firewall and McAfee as the antivirus.On some machines the VB Macros are working perfectly but on other the macros are simply unresponsive.Starts to load then stops but gives no error.Is there anyone with an idea what could be causing this.This started last week and previously all machines were fine.I have tried uninstalling any windows security updates but the problem persists.
