When I launch a notebook interface, sage doesn't work. If I type 2+2 and click "evaluate", nothing happens. However, what is weird is that if I close the window and reopen it, then the answer is here "4".
Also, when I launch sage in a terminal instead, things work quite normally.
I have no idea of what is happening here. It used to work normally, until about two months ago. Since then I have tried everything I could think of, without success:
quitting sage and relaunching it, killing all processes related to sage, restarting the computer,
changing the browser (from safari to mozilla), reloading a new version of sage from the internet...
If anyone has any idea of what is happening and what I should try, thank youSun, 16 Dec 2012 13:24:35 -0600http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/Comment by kcrisman for <p>I have a problem when I try to use sage with the notebook interface on my mac (a macbook pro under MacOS 10.7).

http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18512#post-id-18512Huh, that *is* puzzling. Apparently the calculation is happening (you can even check this by looking at the text version of the worksheet in `.sage/sage_notebook.sagenb/home/admin/11/worksheet.html` (or whatever worksheet number you are in). Also, what happens if you access a remote Sage account, such as at sagenb.org? Knowing more about the exact version of Sage you have would be helpful, too.Mon, 17 Dec 2012 06:15:15 -0600http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18512#post-id-18512Comment by kcrisman for <p>I have a problem when I try to use sage with the notebook interface on my mac (a macbook pro under MacOS 10.7).

http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18509#post-id-18509Hi, does your problem perhaps look like the one at https://groups.google.com/forum/?fromgroups=#!topic/sage-devel/2FI5Fw9ywU8 ? It's conceivable that there is some weird permission problem... also, do you get any error messages in the Terminal when you try evaluating in the browser?Mon, 17 Dec 2012 16:40:44 -0600http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18509#post-id-18509Comment by Joel B. for <p>I have a problem when I try to use sage with the notebook interface on my mac (a macbook pro under MacOS 10.7).

http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18491#post-id-18491Thanks ksrisman for your comments. Things works well when I access a remote sage account. Also my version is 4.7.2. There is no error in the text version of the worksheet. And there doesn't seem to be permission error, as mentioned in the link you gave: if I type ls -l /home/knsam/.sage/sage_notebook.sagenb/home/admin/history.pickle
I obtain -rwx------ 1 jbellaic jbellaic 641506 Aug 31 13:17 .sage/sage_notebook.sagenb/home/admin/history.pickle

http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18518#post-id-18518I think you want to either click the "evaluate" link or do "Shift+Enter".Sun, 16 Dec 2012 14:13:49 -0600http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18518#post-id-18518Comment by kcrisman for <p>I have a problem when I try to use sage with the notebook interface on my mac (a macbook pro under MacOS 10.7).

http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18490#post-id-18490One thing you *can* do is download a newer version of Sage, of course! It's possible that will fix the problem (you say that you tried that, but you also say that you have 4.7.2, which is fairly old by Sage standards).Fri, 21 Dec 2012 01:30:36 -0600http://ask.sagemath.org/question/9640/my-notebook-interface-doesnt-work/?comment=18490#post-id-18490
