(don't know if those "virus" will create some delay on USB signals when it capture messages from USB ports) If you can get an IT guy remove all those junk, or get a clean XP installed on those machines. You may probably get rid of all those issues.

He indicated that no nannyware had been installed. But he tinkered with it a few minutes, said he removed an unneeded firewall. But it made no difference. These same errors occur when asking for an F7 (step): ICD0137: Invalid Adr (MT=0x1) Address = 0xFFFFFFFF & ICD0151: Failed To Sync Memory (MT= data) (Dir=0x0) I notice that no new data values are ever installed into the Register Window. --Bob Axtell -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
