My apologies if this should be posted elsewhere, or if I'm violating some board etiquette, but I was wondering if somebody could help me out. Every time I try to put my pc in stand-by mode, I receive this error message: "The device driver for the 'Communications Port (COM1)' device is preventing the machine from entering standby. Please close all applications and try again. If the problem persists, you may need to update this driver." The problem has persisted (started a couple weeks ago), and I'm not sure what to do. Any help would be greatly appreciated.

To work around this issue, disable the Mrtrate.sys driver. To do this, follow these steps:

1. Click "Start", right-click "My Computer", and then click "Properties".

2. Click the "Hardware" tab, and then click "Device Manager".

3. On the "View" menu, click "Show hidden devices".

4. Expand "Non-Plug and Play Drivers", and then locate the "Mrtrate" driver.

5. Right-click "Mrtrate", and then click "Properties".

6. Click the "Driver" tab, and then click "Stop" under "Current Status".

7. Under "Startup", in the "Type" box, click to select "Disabled", and then click "OK".

8. Quit Device Manager.

This should do the trick

Excellent! Thanks much, DroidC. Worked perfectly. I'll check out the Intuit site as well. Crow, no particular reason - I have the system settings for stand-by after an hour of inactivity - no real reason, I guess. It just started not working a couple weeks ago (after I had the same browser hijack that everyone seems to be getting), so I was hoping to fix it. Again - thanks VERY much.
