I reproduced this. When I came across the problem several days ago,
I also tried to type in 1; etc. anyway, but it did not occur to me
to hit enter twice.
I got a different message when instead of Ctrl-G, I click on the
left mouse button - accidentally, I just wanted to close the maxima
browser, and I got:
Is the matrix 1. Diagonal 2. Symmetric 3. Antisymmetric 4. General
Answer 1, 2, 3 or 4 : Incorrect syntax: : is not a prefix operator

- More precisely, I typed (c5) entermatrix(3,3); <enter>
and as maxima appeared to hang, I then clicked on the "Options"
menu button.
As I mentioned above, I came across this problem several days
ago, but I did not report the bug because I found several
articles/posts (through Google) discussing the problem.
The problem seem to be related to Xmaxima; the plain Maxima works
fine for this command.

P.S. I doubt that this is operating system related (just a guess). I
am using Linux - Slackware 9.0.
