Here's what I found earlier with the preferences files:

There's some incompatibility between the LC6 and LC7+ preference files, 
and afaict it hasn't been resolved yet. The problem is compounded by the 
fact that when you launch LC7+ without a livecode7.rev preferences file, 
it reads the older format and creates a new one for you. This file is 
incompatible with LC7+, and so you end up with undefined things 
happening. If you don't have a previous preferences file then when LC7+ 
creates a new one for you it doesn't have the problems.

So my way around this is:

delete the livecode7.rev preferences file
rename the livecode.rev preferences file to <something>
launch LC7+ -- this will create a new livecode7.rev file for you
rename the <something> file back to livecode.rev

you now have both livecode.rev and livecode7.rev files in your 
preferences folder, both will work with their respective versions, but 
of course you need to configure the LC7+ preferences because now they're 
all the defaults.
