How can I stop big windows from resizing when I lock my workstation?

I have a multimonitor setup on Windows XP x64.

If I have a window sized to be larger than a single monitor (say, a web browser that's wide enough for 2 monitors), and I lock my workstation, it will be resized down to a single monitor when I unlock the workstation.

Is there any way to stop this behavior?

Solution 1:

It could be a driver problem. I had a similar problem with an old laptop. No external display, but there was still one listed in the display properties, set to a low resolution. Whenever I closed the lid of my laptop, any windows were shrunk, possibly to the size of the ghost display.

It doesn't sound like the same problem, but this may be another clue to the mystery!
