I'm a Chrome user and I too have spacebaritus . .
Disabled pepperflash and when I launch WGT the box on the left with friends list and play now button doesn't come up.
Tried Maxthon and Firefox browsers and although the spacebar issue is fixed . . . the meter isn't very smooth.
C'mon WGT / Flashplayer peeps . . . sort it out please!
For once, the company can't do a thing. It's our local IT admin who has to care.
1) Your description shows that you have no Flash except Pepperflash installed. If you disable it there ain't none left to use for playing.
=> Get Flash from Adobe.com as described in many words in the link given above and pray that the spacebar issue be solved.
2) Using Maxthon, it's essential to get Version 3 (link on the bottom of Maxthon's site). Maxthon Cloud is Version 4 - not as good IMHO.
3) Using Firefox, it's essential to get the latest Flash version 11.7 (.700 here) because former versions caused severe problems, crashes and such.
