Successfully installed the WordPress Mobile Pack and I am using a custom theme (modified version of the mobile pack base theme). Seeing issues arise where at times certain pages of the site on desktop are showing mobile theme and other times desktop. I am able to duplicate this issue on a number of different computers/browsers. For the WordPress Mobile Pack plugin, under Mobile Switcher options in admin, I have switcher mode set to browser detection and browser detection set to user-agent prefixes. Not sure why this issue is occuring.
