Re: Kernel crash, version 7.0, windows XP, when using slider in Manipulate with Dynamics plot on control area

Thanks for trying it Bob;

I do NOT get the crash when I edit the control label directly as you 
described. Interesting.

The crash happens only when I open the animation controls by clicking on the 
"+" to the right of the control and type in a number such as 1 in the little 
white input field, then move the mouse and click on another control.

As I said earlier in an email, this problem went away when I use 
SynchronousUpdating -> True. Kernel does not crash any more. Only when 
SynchronousUpdating -> False, and using Dynamic Plot inside the control 
variable area, that this crash happens.

File:
http://12000.org/tmp/bug_input_slider/

it is called filter_v9.nb

The fixed file is called filter_v10.nb


XP, SP2, Mathematica version 7

thanks,
--Nasser
