I also have this same issue occassionally. It's due to the resolution of the computer's display that the user has set the computer to.
If I ask the user to set it to a lower resolution, I can then control the computer. I work in a school environment & from time to time, the teachers change their resolution to fit their needs for displaying or for their eyesight.
I have been looking for a Unix command that would change the resolution remotely without needing someone physically at the machine but have had no success yet & haven't taken the time to try to build one myself yet.
Hope this helps.

Thanks for the update, Laura.
I guess this means Apple isn't going to fix it. Seems absolutely ridiculous to tell the user to lower the resolution to something crappier so that I can remotely control the computer. Of course, most of my users wouldn't know how to do that in the first place. I could rant on, but that doesn't serve any purpose except assuage my contempt for the apathetic arrogance of many programmers. (And it's not just Apple.)
I think you may be on to something though. I'm thinking that maybe I can push out a preference - restart the computer and have it reboot to the desired resolution? I'm looking at the com.apple.windowserver.plist file and it looks like that might be the one to use. I'll have to fiddle and futz around with a laptop and figure out what the right resolution is.
It's CLEAR that when you connect a VGA adapter that the screen resolution changes to accomodate the projector (we have old ones, so the resolution gets crappier - reduces to 1024 X 780). When you disconnect the adapter, then the resolution changes back to the "default" (or what it was before the adapter was connected). HOWEVER, teachers are NOT disconnecting the adapter, they just turn off the projector. Even so, the resolution on the laptop changes back to the default, but I'm guessing there is something else going on.
I think what I'm going to try is to enable VNC and then find a good VNC program to control the laptops.
Sigh...soldier on...so lonely in the IT closet...
