Hey Mike, I also recently purchased Vue 4 for Mac OSX and I've had my share of crashes. Not as often as you seem to ... but some instances are repeatable. I don't have any answers for you. Have you been in touch with E-On? There U.S. contact is Lynn Fredricks, nice guy, and he does post to this forum. Hopefully the 4.2 update will be ready soon, hopefully it will address some of the bugs. - Dave
