I was wondering if someone has a real Mathematica debugger that they could
use to help me find where this bug is? I do standard mathematica.
I spend the last 6 hrs on this, and can't find the problem. I do not have a
debugger, so it is impossible to find where the bug is since it is a kernel
crash and I do not see what I am doing wrong. One thing I know is that if I
all the Epilog code in the code, the problem goes away.
This is the problem:
I have a manipulate, with a plot being drawn using Dynamics in the control
area. The plots uses control variables.
When I enter a value of a control variable using the slider (i.e. normal
method) there is no problem. no crash, even though the slider goes over the
same input value which will cause a crash when I enter this input as
I open the slider by clicking open on the small "+" next to the slider, and
type in a numerical value, the kernel crashes.
For example, There is a control variable called zeta in the program. When I
move the slider no crash happens. When I open the slider window and type in
a value then the crash happens. The strange thing, if I type in "1"
instead of "1.0" then it will crash, but if I type "1." no crash is seen
(i.e. add a decimal point !)
I have a screen shot here to help you see the problem:
And the notebook is in the same folder, here:
it is called filter_v9.nb
All what you have to do just download the notebook, open it in Mathematica,
open the slider input area just like shown in the above image, and type in 1
Next, simply hit any other control with the mouse to activate, now the
kernel will crash.
As I said, if I type 1. instead of 1 (i.e. with a decimal point), the
problem does not happen.
Any one has version 7.0.1? does the problem happens with it also?
