v.1.1.4 fix 3 geometry

[john gennard]

I've just installed the above and want to start the learning
process. However, on launching Lyx I'm faced with a window
which is to large for my screen and I dislike using a virtual
desktop. So far I've been unable to locate the file which
contains the default geometry setting, so cannot make changes.

Can someone please let me know how to permanently alter
the window size.           Thanks, John.
