Can I stop my CRT from turning off and back on again during fast user switching?

My CRT drives me nuts by turning off and on again every time I switch accounts using fast user switching. Can I stop this?

I noticed a similar issue on my mom's computer but didn't try to do anything for it.

Does every user account have the same screen resolution set?

Does every user account have the same screen resolution set?

Yes, each account uses the same resolution.

The CRT turns off and on twice per switch--once when it switches to the screen that gives you a choice of user accounts and again when it switches to a particular account.

The only thing I can figure is that the welcome screen is set to a different resolution. I don't know though.
