There's one small detail in Vegas which I find a bit
annoying: If you open a file, then select "Save As.." , it
will open the directory where you last saved something -
not the directory where the file you just opened, is. In
most other programs, it's the other way around.

However, don't touch the "Render As.." settings. The fact
it remembers where and how you last saved is a GOOD thing.
Especially when you have to open, then render a large
number of files to another directory.

I have a very large number of small files to deal with (as
I'm working on a game project), so I've occasionally dreamt
of some kind of a batch exporting function..
