Mathcad Prime 4.0 still not so prime

Certainly not,

see e.g.: Prime 4.0 features worth upgrade?, and Update with not Much Prime 4.0 to mention a few very recent ones.

I guess with " it ***** " you mean: it extracts substance using underpressure...?

I think everyone agrees with you.  What puzzles me is business decisions PTC is making.  Mathcad has a well recognized name, passionate followers and fills a niche that millions of engineers would find advantageous.  If they got it right (again) they could easily milk the program for a decade before a serious update is needed.  (See Excel.  That is a cash cow that requires little input.)  I understand that 15 was looking dated and I have nothing against the intent of Prime.  But the hard part was already done (getting a computer to do math); what's so hard about updating that to a new system?  And instead of fixing what the users really need, they put resources on implementing OLE.   Nice but in no way is that a priority.

In order to help PTC out, here is a plan. 

a.) Fix the small bugs in Prime.  Just the way the screen shifts around and selecting boxes get messed up.  There is no point in adding more advanced features if it can't do the very basic function of having a robust GUI.  I can't sell a program to others for engineering calculations if the mouse doesn't work right.  I can't imagine this would take more than a month. 

b.) Make it the engineering calculation tool it needs to be.  Without that set, there is no point in working on integration with other PTC products or adding OLE.  That means fixing the more serious bugs and adding universally needed features like improved plots. 

c.)  Once your tool is stable and solid, continue to add functional features.  Examples would be more advanced plot types (beyond what 15 has) and better conversion of legacy files.   

d.) Distribute mathcad freely to all engineering universities.  Build your base of users there.

e.) profit

It's hard to believe that anyone would pay for this upgrade. It's astounding how little was improvement was made in two years. The lack of discussion about 4.0 in this forum suggests that users have reacted with a big yawn.
