Yes, great, thanks for pointing out the way to get a debug log

A more full version of the log with all the preamble is at pastebin:

But the problem appears to be that PresenceVNC sends the Shift and Fn keypresses as well, and they are applied server-side by X11VNC, effectively cancelling out the application by PresenceVNC that was done before sending to the server:

Code:

07/09/2010 10:12:18 calling XTestFakeKeyEvent(28, 1)  176.0178

07/09/2010 10:12:18 # keyboard(up, 0x54 "T") uip=0  176.2423
07/09/2010 10:12:18 modifier_tweak_keyboard: up keysym=0x54
07/09/2010 10:12:18 modifier_tweak_keyboard: KeySym 0x54 "T" -> KeyCode 0x1c

07/09/2010 10:12:18 calling XTestFakeKeyEvent(28, 0)  176.2424

A similar thing happens with Fn+Space, with PresenceVNC sending a "ISO_Level3_Shift" down event, followed by an "at" character, which X11VNC then converts back to a "2" because the L3_Shift is applied.

Thanks so much for your help.
