Similar experiences here, except this is the first time RB has been
installed on this computer so 4.7 vs. 5.0 compatibility issues won't
exist for me (new job, so I'm working from a clean install -- I have
plenty for RB experience from a prior job, so I know how to use it). I
can only make extremely basic queries work. I spoke to my old co-workers
and 5.0 made RB un-usable to them.
In principle, the new menu looks cooler -- is more sleek -- but
everything is much harder to find, with many more clicks needed in order
to to find what is needed. Yes, we could use the search box, but Adobe's
desire for us to use the search box doesn't mean they should make the UI
for the menuing system worse.
