..........Just for the halibut, i downloaded the recent MINT cinnamon/xfce ....ran a you tube- video =worked on LIVEcd but with NO SOUND.
...Updated the flash packages and the same
BLACK BOX shows on you tube.......SO it may
not be ANYTHING to do with PCLOS - maybe with
LINUX "adobe" flash and FIREFOX #12....just for the record, and info for our great DEV's...

EDIT: FYI The clients video card shows:
VGA compatible controller: nVidia Corporation NV15GL [Quadro2 Pro] (rev a4) and I ran a
2011.09 LIVE lxde CD and everything works perfect...also checked the packages and FLASHPLAYER plugin is 10.3.183.10-1.....and Firefox is 7.0-1....I'm wonderin if a person should even update "older" machines ANYMORE?......it has an 1800mhz AMD DURON and vt8233 onboard sound....It seems problems occur after "updates" ....

...These things turn a client off.
