yanay on "[Plugin: WPtouch] WPTouch not reading .mo files"

I did place it in wp-content/wptouch/lang. It's theme's .mo file created using PoEdit. Should it be the plugin's .mo?
.mo file in WPTouch lang directory has no effect - my home page on desktop is losing translation. When deactivated all is well. Why is WPTouch modifying my desktop site? It should only affect the mobile version of the site.
