I think Lyx doesn't handle well commands like \left\{,
\right\{
Try \left\lbrace and \right\rbrace.
\left(, \right),
These work fine for me.
etc. from the user interface.
Especially try the ones for braces, you'll see what I
mean. Interestingly, when you write first
\left( \right), and then place the cursor between
the parentheses, Lyx allows you to write between
\right and ) for example. it's hard to notice this,
as the only visual hint is an invisible slim extra
space before ) caused by \right. This causes latex
errors.
I agree that this comes as a bit of an ambush the first time. There is
another visual cue, though. Look at the status line at the bottom of
the window. When you are between \left or \right and the corresponding
brace/bracket, you'll see 'Symbol: left' or 'Symbol: right' at the end
of the status message. Once you get used to the fact that the \left or
\right command is treated as separate from the bracketing symbol, and
learn to keep an eye on the status line, it's not too bad.
