When copying a command into the IDE/GUI terminal that has a lot of non 
alpha-numeric characters such as parentheses and brackets, the 
processing is really slow.  Something like this:

qtinputdlg ({"Einstein:","Newton:","Planck:"}, "Most General Example", 
[1 7; 1 11; 1 20], {"E = m c^2","F = G m1 m2 / r^2","B = 2 h v^3 / (c^2 
(e^(h v/(k T)) - 1))"})

takes several seconds to process.  A stream of text zips in up to the 
closing bracket, then stops for a half second.  Then another stream of 
text until a bracket is encountered.  Etc.

Copying into a shell command line is speedy in the most recent source. 
However, I think I've seen a similar sort of thing even when not running 
the GUI on a version from a couple weeks ago.

Does anyone know why that is happening?

Dan,

I've been seeing this too in both the GUI and the CLI version of Octave.  I thought it was just me, because I just upgraded my OS, but maybe it is more general.

Have you tried starting octave with '--no-line-editing' which disables Readline?  That fixes the problem for me, but I really rely on the readline library so it isn't a good long term solution.
