Lion Won't Wake For Incoming Network Access

Hello, All:

After Lion upgrade I cannot get my remote access program (Timbuktu) to show my desktop to remote users. The sleeping screen (not the hard drive) is set for "Wake for network access" and all other settings are checked and appropriate including an update to the newest Timbuktu 8.8.3.

The screen wakes from keyboard or trackball activity but not for incoming access.

Note: The remote user sees the frame for the desktop in Timbuktu but is shows a sleeping (dark) screen. The file and clipboard exchanges still work but the screen ignores the instruction to wake.

Access worked perfectly with Timbuktu until three weeks ago. Then it just sleeps like a teenager on Saturday morning unless tapped on the shoulder by a parent. Call-ins don't get answered. ;-)

Any ideas would be dearly appreciated.

Thanks

iMac, Mac OS X (10.7.4)

I have 8.8.4 and Mountain Lion and the display still does not wake up after I wake the system with a WOL packet. I'm grateful for the information about using caffeinate to wake the display. Maybe it works if only the display is sleeping but not the system. But it doesn't work if the system was sleeping, and is awoken via a WOL packet. The system is awake but not the display. The workaround to use caffeinate at a shell prompt after ssh'ing in is necessary for me.
