Wow, if those two are true, those are pretty bad bugs.
Also, the media management isn't always very clear. You have this great potential of the Events and Projects, but like TrixTrax said, sometimes you just want to copy a project somewhere, and even though you think it would only copy the project itself, it goes ahead and begins copying media.
I do think that (again, I haven't tested the bugs, but I'll take your word for it) with bugs like that, Apple needs to get their stuff in order.
FCP X has a very bad reputation, and the updates have helped a lot. Still having bugs like that after a year, which is the phase in which sceptic people were believing FCP X would finally be able to be taken serious in the NLE world, having new bugs like that is a killer.
BTW: not saying FCP X is professional or not, but talking about the perception people have of it. Apple did some things wrong with the launch, that they should put their best programmers on it and put some serious work on this app if they want to grab more market share.
