(new) Down-arrow button in examples can crash session --mdc, Tue, 19 Apr 2005 10:21:29 -0500

Axiom 3.4 (April 2005), compiled and running under SuSE 9,2,

This is an intermittent fault, happening more than half the time. Occurs 
when logged in at console, also when logged in by ssh with X-forwarding 
(from SuSE 9.1), and from a Win PC by Hummingbird exceed. Nothing is 
logged in .xsession-errors.

Actions to reproduce fault:
1) Start axiom, as above.
2) In HyperDoc window, click on "Examples", then in next window on 
"Graphics", then on "Assorted Examples". Now click on the first down-arrow 
icon, following "Function of two variables: z=f(x,y)". (Also happens for 
other examples, of course.)

More than half the time, all windows vanish, except for the initial 
terminal window (in which one typed "axiom").

There are no error messages.

HOWEVER: If instead of clicking on the down-arrow, one clicks on the 
"draw" command next to it, the command executes in a new terminal window 
without problem. Clicking on the down-arrow subsequently displays the 
graph in-line, with no crash.

Also, typing that draw command into the original terminal window, one gets 
a plausible graph.

Have fun,
