I can reproduce a crash everytime in Parallels build 1918 with Windows XP SP2 as my guest OS. This bug is also present in the 1910 build. If I mute the VM using the control located at the bottom right and then "nudge" someone in MSN Messenger the VM crashes without fail. Playing sounds in iTunes doesn't crash the VM but I haven't try any other applications at this stage. Anyone else noticed this type of behaviour? Cheers, Phill
