That actually leads to another question.

Why isn't Maple able to work with its own predefined constants? I mean, what exactly is the meaning of "use Pi for calculations" according to the help file.

Regarding the conversion - this is something new in Maple 2022.

@Preben Alsholm 

I could do at least 3 other methods to go around the problem again, but frankly speaking I'm fed up of the Units package.

There are far too many bugs in this implementation, and apparently its gets worse.

Apparently the solution is to use evalf on the contents of alpha.

I'll add this one to the list...

About 3 years ago we came to the conclusion that Mathcad wasn't worth the bucket anymore, and we landed on Maple as the alternative. By coincidence, both software houses have now delivered their new releases.

And the situation is the same as the last couple of years. While I would need about a day or more to dig through all the changes of the Maple package, the new things on the Mathcad front are, well, limited.

So on that front a big applause to the Maple development team.

I do however have a couple of issues that I am not so happy with, and that need to be addressed as soon as possible.

• Maple still hasn't any functional system in place to prevent two users from opening the same workbook. The last to save wins is not a game we want to play in our office. This is basic functionality that is lacking, guys, and you've been made aware of it for quite a long time now.
• The units package is still a mess. The biggest issue is that variables miss their unit when their value becomes zero. In addition some functions miss part of their functionality once you add units.

On the other side, Maple 2022 seems to be more responsive, and has fewer graphics glitches than we had previously. 

Autosave finally seems to work for workbooks as well, and some progress has been made on the pdf printing front.

@vv 

That's exactly why an exemption should be raised in that case.

Contrary to plan Maple, the Units package doesn't implement the [index] functionality anymore, thus it is unknown.

If the max function doesn't ignore wrong indices, the max function in the Units package should'nt do either.

Apparently fixed in 2022.

@Karen 

Solution verified.

However Maple Help still only mentiones autosave for worksheets, not workbooks.

No change in Maple 2022.

Windows Defender, protected folder access blocked.

And the program doesn't tell anything, so one needs to dig into the logfiles...

@mmcdara 

Same result with forward slashes.

Btw., the filepath was copied from Maplets(Elements) FileDialog.

The file directory checks don't show anything unusual.

For ExcelTools:-Export, it actually doesn't matter if the file exists, or not. It will overwrite it, if possible. But for the records, there wasn't any file with that name in that directory.

The IsLockable doesn't exits with an error message on my PC.

You are right, it looks right when going to another document and back again.

That's what it looks like when I change settings afterwards again.

@Anthrazit 

Got feedback from the service team, that this is going to be fixed in the next release.
