In the below plot switches between to solutions of a RootOf expression when the plot range starts at zero.

plot3d on the other hand sticks to one root.

Why is that and how to get a plot starting at zero showing only one root?

restart

a := RootOf(JacobiCN(sqrt(2)*sqrt(alpha), (1/2)*sqrt(2)*_Z)^2*_Z^2+_Z^2-2)

RootOf(JacobiCN(2^(1/2)*alpha^(1/2), (1/2)*2^(1/2)*_Z)^2*_Z^2+_Z^2-2)

(1)

allvalues(a)

RootOf(JacobiCN(2^(1/2)*alpha^(1/2), (1/2)*2^(1/2)*_Z)^2*_Z^2+_Z^2-2)

(2)

plot(a, alpha = 0 .. .5)

 

eval(a, [alpha = 1/20])

RootOf(JacobiCN((1/20)*2^(1/2)*20^(1/2), (1/2)*2^(1/2)*_Z)^2*_Z^2+_Z^2-2)

(3)

evalf(allvalues(RootOf(JacobiCN((1/20)*2^(1/2)*20^(1/2), (1/2)*2^(1/2)*_Z)^2*_Z^2+_Z^2-2)))

When I insert a link to a worksheet Maple 2025 crashes (also with the Screen Reader version).

When I click on a hyperlink to a workbook in a document created with Maple 2024, Maple 2025 crashes.

Is this reproducible?

Edit:

Also opening a workbook crashes Maple 2025 (i.e. no hyperlinks involved)

I get this message:

Why is it not working using the menu?

In the attached document (an excerpt from a larger document) is a call to the interactive plotbuilder.
The call is somewhere hidden in a document block but the document block with the redline is empty. Deleting the document block only moves the red line to another block. 

Executing the entire document (with !!!) starts the plot builder, execution step by step (with !) does not.

How to delete the call to the plotbuilder?

Why are characters printed with additional back ticks when decimal HTML code is used (see output (3) below). lprint((3)) does not print them.

Looks like an exception. Is there a reason for that? Can it be used for something?

With HTML entitiy

(1)

With HTML hex code

(2)

With HTML decimal code
