I use Control Panel/Scheduled Tasks to run certain programmes at set times. Until a few weeks ago the scheduler would activate the programme even if the computer was in standby mode. Recently however this no longer happens and I get the message 'Could not start' or 'missed'. My OS is Windows XP Home and I have both Microsoft Anti-Spyware and Norton Antivirus installed but they were present when the scheduler operated satisfactorily. Has anyone any idea what has changed?
