I tried Maple 2023, then downloaded Maple 2025. Maple 2025 was worse.  

So I reverted back you Maple 2023.

This is what I wrote and saved.

I closed the file and reopened, and it flashes on the orginal style then converts to

Any suggestions are appreciated.

Thanks for the suggestion.

The problem is, I can enter everything fine, the font Time Roman 28 etc. tthat I want.

But if I save the file, then reload it, the font changes to Courier, 12 pt. 

I use in Maple for teaching, and I like the large font so that the students can see the programs.

This problem just started today, was there an update? Maybe it is a bug.

@Carl Love 

Thanks for the suggestion, but no luck.

I can enter, but when I reopen it defaults to Courier.

Thanks, this was helpful.

I was able to use Maple 2023 to reopen my files, thankfully no data was lost. 

I was able to change the Display setting in Maple 2023, but can't find how to change the Display settings in Maple 2025.

Any idea?
