Bonjour Florent,
Thanks for the suggestions.
(1) None of these options worked to get back to mouse *outside* of the sage/VM
window. The only way I could get the mouse back for the rest of my desktop was
to do Control-Alt-Delete, tell the machine I was logging off, and then
cancelling when it asked me to force shutdown of various programs.
(2) Here is precisely what I am doing: Starting Oracle VM VirtualBox, typing
Control C twice to quit the Sage notebook, this brings up the prompt
[sage@sage sage]$
in the VM screen. I then type
./sage
This brings up the prompt
sage:
in the VM screen. Then I start trying commands in the VM screen, for example
if I type
sage -i dot2tex
then I get the error message
File "<ipython console>", line 1
sage -i dot2tex
^
SyntaxError: invalid syntax
If I try
./sage -i dot2tex
I get the same error message except that the caret (^) points to the period in
"./sage"
Cheers, Bruce

Have you tried Escape ? Shift+escape ? Ctrl+Escape ?

What is the precise error message ? Are you in the right directory ? Did you
try ./sage ... instead of sage ...
Cheers,
Florent
