something on your machine....
no major changes in the release
why would the line-in unmute anyway? the only way it would if something asks it to
sounds like something it writing to your rr.ini (rr wont do that on its own)
cpu% flash issues... are u at the latest flash? see sticky
usually 1st thing i say, is use carwings_dynamic_lite
(this time its not the 1st thing... but still applies)
also.. before you say i have it checked in rrconfig... id look at rr.ini directly in text editor
