Does anyone have the following problems with Prime 1) Spurious jumping to other parts of the document - especially when swapping from Doc to Draft view or when opening embedded Excel sheets - very dangerous as the second click puts you into an area where you might accidentally make a change 2) Random placement of collapsed areas when trying to separate one are one another - a bit like Word when trying to move images around - they end up somewhere lost in the larger document - again resulting in a scrambled order of code if not careful 3) Poor visibility of cursor in highlighted areas - making it difficult to edit or copy expressions ? 4) Spurious jumping to other parts of the work sheet if you alter the zoom? 5) An uncertain size limit on the variables you can transfer into the excel sheet forcing you to use more than one spreadsheet 6) A random Inability to view or edit expressions in draft view that are wider than some arbitrary page width setting - in draft view we should be able to see the whole formula - sometimes Prime wakes up and lets you see the whole expression sometimes it does not - changing grid size sometimes make Prime wake up 7) Any suggestions on how to improve the appalling graph plot options - a tremendous backwards step from proper MathCad - adding grid line would be nice ? 8) Losing a small part of the worksheet on the left hand side of the screen that cannot be seen no matter how the window is sized or adjusted ? 9) Random ability to open or collapse an area when in draft view - cant just see the button? 10) An inability to paste variables from worksheet in to the Find or Replace-With window - instead it gives @LABEL VARIABLE - which it then fails to recognize as a valid search term?  1-Newbie

Yes, I have these problems too: 5-10.

And I can't sign axes and timetable like Mathcad 15.  10-Marble

Hi, @GeoffD!

I think your message should be in some other thread, probably in a separate thread, because it has nothing in common with the initial topic.

We addressed the "spurious jumping" problem(s) in Mathcad Prime 6 or 7 so if you do not have the latest version installed please upgrade. If you still see the problem in Prime 8 - please report it to technical support.

2 "Random placement of collapsed areas" - I am not sure I completely understand the problem, but we might have something similar in our backlog. Might also be a good idea to report to tech support with exact steps to reproduce and sample worsheet.

9: Just try to scroll left. The button is there but it scrolled out of view.

10. This is a known limitation. Find and replace can only search for plain text. When you copy a math. expression or it's part it would copy as S-expression representation of the expression. If you paste it to a math region or to a worksheet it will create a copy of the original math. expression. Paste to find or replace box leads to the unexpected result that you describe. We plan to add search for math expression and for other usages of given variable in future.  12-Amethyst

Thanks for the feedback - I put these in some time ago and Prime8 has improved things considerably - especially on stability. Things are still a bit jumpy when moving between areas and the worksheet when it jumps back to earlier places but at least I know what's happening.

Many Thanks
