We have just run into a problem (loss of data), when 2 users have opened the same workbook.

Does Maple support Multiuser access to a workbook, and if not - why isn't there any lock mechanism in place to prevent that?

Why are units disappearing in this expression?

The answer should be 0 kN, not 0.

Is there any possibility to define which units are used in components, like MathContainers?

I would like to have kN/m, I get mm2*kg/m3*m/s2...

What have I done!

Whatever I have created - Maple doesn't think it is a list.

The question is - what is it then?

proclist.mw

Is it possible to define variables with "unit" % or ‰ in Maple?

c:=20%

does not work, it apparently gives you 20 multiplied with the result of the last calculation.
