2014-11-16 17:50:48 +0200 asked a question evaluation button in sage notebook 6.4

Dear all,

I have just upgraded to Sage 6.4. But now, when I use the notebook() environment, there is no evaluation button after a block. Also, pressing shift+enter only starts a new line, but does not initiate evaluation?

Currently my only option to use the evaluate all functio, but this is unsatisfactory.

What can I do?

Thank you in advance.

EDIT: This problem seems to be firefox related, since in safari I have the option

It seems is have gcc4.9.1, since sage told me so when I attempted to install sage 6.4. But I encountered: error: "found MacPorts in /opt/local/bin/port. Either: (1) rename /opt/local and /sw, or (2) change PATH and DYLD_LIBRARY_PATH (Once Sage is built, you can restore them.) If you would like to try to build Sage anyway (to help porting), export the variable 'SAGE_PORT' to something non-empty. make[2]: *** [/Users/Alex/Downloads/sage-6.4.beta4/local/var/lib/sage/installed/prereq] Error 1 make[1]: *** [all] Error 2

Thank you for your comments. I am using Sage version 6.3, released 2014-08-10, and have recently installed gcc4.9 via macport and set it to default using gcc_select. Hope that is the relevant information.
