With the update of Maple 2025, I'm finding that every time I open a saved Maple worksheet (from say my desktop or File Explorer), Maple creates a new window rather than opening the worksheet in a previously opened window (as previous versions of Maple have done). 

Is there a way to prevent this? For context, I'm running Windows 11. 

Is there a way to map a neutral operator "&^" over a list L := [a,b,c,d], so that the output is a &^ b &^ c &^ d. 

I can do this with a loop, but I'm wondering if there is already a built-in function for this.
