Presentation Director is a very helpful utility that sets up multi-monitor profiles. It comes preloaded on Thinkpads (T60 in my case). It handles a couple things that Ultramon does not, such as turning on the ThinkLight (keyboard light), using a specific monitor profile when docking the laptop, moving the "primary monitor" to a secondary display (where your start menu will be), disabling screen saver and standby upon applying presentation scheme and a few others. It's not just for "presentations" but for managing multiple monitors.
This happened to me before, but I didn't put together the fact that it was Ultramon causing it until I installed it this last time.
After installing Ultramon I loose two capabilities in Presentation Director. The first is the ability to move my Primary Monitor (or Desktop) to the external monitor - instead Presentation Director thinks it successfully applied the scheme, but the desktop is mirrored on both monitors. The second is Presentation Director complains that it cannot set the external refresh rate for an attached external monitor.
The interesting thing is that when I installed Ultramon without a reboot (it didn't need one) everything worked fine together. After a reboot these items no longer worked. After uninstalling Ultramon, everything works again.
I will mention something else about my setup that I think is not related because I had this problem before with Ultramon with a standard external CRT as well. I have the Gateway Wide Screen LCD (FPD2185W) which has additional drivers loading for pivot detection and color profiles.
I would like to run ultramon for it's dual taskbars and easy switching of a window to the secondary display. The ATI hydravision drivers do not work reliably to switch apps to the other monitor. Ultramon does work wellwith ATI Hydravision's desktop manager which I use a lot when instructing.
Anyone dealt with this before or have a solution?

Sounds like a compatibility issue with UltraMon's mirroring feature, removing the mirroring feature should fix the problem.
To do this, go to Control Panel > Add or Remove Programs, select UltraMon from the list, click on Change, then deselect the mirroring feature on the Customize Installation screen.
What probably happens is that Presentation Director sees the mirror driver used by UltraMon's mirroring feature as an additional display, and then tries to apply settings to this display. The correct behavior for Presentation Director would be to ignore the mirror driver.
You would only see this issue after the first reboot because the mirror driver doesn't get loaded until after the first reboot.
