Why "local D" prints D not in ...

In the below I was looking for an explanation why D is not printed in italic whereas I does.

 (5)

whattype(D)

 (6)

_local(D)

NULL

After the local call D and I are both symbols but not printed the same way. Why is that?

With the new ribbon interface (and startup-page disabled) I need to open a new worksheet to make opening files by the recent document menu work.

Can someone reproduce this?

I write text in Trebuchet MS. When inserting footers I have noticed that the print preview displays page numbers not with the same font (most likely in Times New Roman).

How to change the font of page numbers and other items in headers and footers?

The double indices in the above limit do not make sense.

In case this is a bug: Is there any workaround for indexed names? I want to use them to have numbers in indices in roman which seems to be not possible with subscripts.

Why is Maple 2025.1 not listed in Window...

To organize windows, Windows 11 provides a new function "Snap Layout". The example screen shot below shows options to place the Maple 2025 Screen Reader window.  

Ein Bild, das Screenshot, Reihe, Software, Multimedia-Software enthält. KI-generierte Inhalte können fehlerhaft sein.

Draging now Maple 2025.1 Screen Reader to the left window of the third option results in the following selection screen

Ein Bild, das Text, Screenshot, Software, Computersymbol enthält. KI-generierte Inhalte können fehlerhaft sein.

where on the right a list of tasks to chose from is presented. In this list Maple 2025.1 is missing. However Maple 2025.1 was running as can be seen from the task bar.

Has anybody managed to position Maple 2025.1 windows with the Snap Layout (or alternatively with Win+Arrow keys) or at least reproduce what I see on my computer?

Why can a Maple 2025.1 window be adjusted by hand but Windows does not do this in Snap Layout?

(Dragging and adjusting a Maple window by hand is not an option. This is how we had to work before Windows 7.)
