Question about upgrading
 

Hmm, I haven't upgraded in a while now (well, actually ever since I dlded LW I've never upgraded it).
You see, I have this little fear: if I DO upgrade, because I want to do it, will my incompletes be erased or sumthin'?
I've been trying to get a really elusive video for, like, ages now and would hate to see the newest version of one of my prefered apps forget what it's "ancestor" was doing.
So, speaking to the more experienced out there (or at least to those who have upgreaded at least once), tell me what to do.

I have a feeling that everything will be fine but...

all stays the same--the OSX installer just updates whatever files are needed. In fact, I usually have to check the About box to make sure the update is in effect.
