Great, this is much better:
	-icons are displayed nicely
	-bars are OK (at least the few I've seen)
	-heartbeat icon flashes nicely in the top right corner.

Only issue I encountered was (similar came up before) - when setting some menu 
options, or just entering a certain menu (like Options->CwLnx->OnBrightness, 
lcdvc client menu), the LCD becomes garbled  (i.e. displays two blinking hearts, 
boxes, '%' symbols), sometimes starts displaying just '%' symbols over the whole 
LCD while I'm pressing Left/Right keys (is this the screen-saver?), scrolling 
from right to left. Even the "Thank you for using ..." message is garbled (each 
time in a different way) if I kill the daemon after that. Pressing 'X' when the 
garbled characters occur exits the menu and the other (client) screens are 
displayed correctly after that. So only the menus are affected by this issue - 
it seems that this screen-saver mode kicks in in the wrong time, and tries to 
write to LCD faster than it can process chars/commands.

I can provide the log file if you want ...
