i recently noticed that i can no longer access maple transactions, usual link https://mapletransactions.org/index.php/maple/index automatically opens https://scholarsportal.info/, and in that web site, some pages do not open, stating

"The page you are trying to access is restricted to IP addresses from our member universities. Please try accessing this page from on-campus or through a VPN."

this seems like a geo ip restriction, i search for an announcement for this change but i couldn't any, could you please clarify situation?

thanks in advance..

I couldn't set plot view ranges for plot component (in the attached worksheet). How can i do that?

example worksheet has to draw an ellipse whose center coordinates are determined by two sliders (lef tslider for x, right slider for y). I used following callback function

Do ( xpos = %xPos );
Do ( ypos = %yPos );

Do( %Plot0 = plots[display]( plottools[ellipse]([xpos,ypos],3,4)), view=[-10..110,-10..110],axes=boxed );

When i try setting this task at prompt, it succeeds ...

I want to disable automatic simplification for certain operation(s), for example, instead of usual response
