Slight update.
Even if you use SlideMe for your market searching, it will still reboot Android (not boot back to WM, you will just be taken back to the HERO screen), that being said I still recommend it over the regular market
That being said it definitely isn't a program issue Klinux said in the other thread that he is already aware of and working on it.
Also I have experienced problems with Android going into a SOD, my (temporary) work around is turning off the backlight options in WM before boot. My buttons stay lit now, but I have no problem waking my device.
