Don't know how helpful this is, but I forgot to mention that this did happen to me for a long period over a year ago - I can't remember how it was fixed though.

Thanks for the info, OneOfSand. We are looking into it   

Yes, I had problem like this. "Cannot create nVidia control panel - version mismatch"

Any answer on this yet?

I also have this problem. I formatted my Windows partition and reinstalled everything, but here is my current setup: Windows XP Pro (SP2 with _all_ of the Windows Update patches applied), NVIDIA Quadro FX 3000 (drivers v91.36 [non-beta]), 4GB RAM, Logika suite), with 48x48 icons. I can tell that when Windows first launches, the icons are placed where I left them, but as soon as the rest of Object Desktop launches, they revert back. I can also get this to happen if I change anything in the OD settings. Another non-icon-related issue is that explorer.exe _always_ hangs when I either restart or shutdown. I don't know what the cause of this is. In another non-related issue, the Device Manager window is completely blank (just the frame opens). If I right-click inside the window, Windows thinks I right-clicked on the Desktop. I literally have just the window frame; no contents.
