right, firstly i'm running MP on a TV as primary display and everything else on a CRT as secondary. i know that's not supported but i dunno how much that's gotta do with this, so i'll just mention it incase anyone else has the same problem...

every now and then when MP's running, i get a strange high pitched squeaking noise coming from the hard drive, which is mostly normal i guess. the weird thing is that it stops, either when i select the media portal window (via the task bar) if it's unselected, or select something else if it is selected when the squeaking starts. so it's possibly something to do with searching the hard drive, and maybe a graphics drivery thing due to the dual monitor setup. but like i say, just thought i'd mention it, it seems kinda wierd.

ick, while i'm here i might as well: 0.2.0.0 RC1 really don't like multitasking. anything else using the CPU makes it stop playback and give me a window saying "this is a scambled channel blah blah" with a wee quality bar going up and down.
