Front End Issues in Mathematica 10

Posted 11 years ago

I have several, possibly related, problems with mma10. Here are some:

1) If I type a centered equation such as xa;b in which the "a;b" is a subscript, the whole subscript vanishes as soon as I type the "b". If I delete the "b", I see xa; . This is a real problem with notes on the covariant derivative.

2) If I highlight a word in a text cell and type Alt+rxr, all the text in the cell turns red. If, instead, I type Alt+rx, and then use the mouse to click on "Red" in the dropdown, it works fine.

3) If I highlight a cell bracket and type Alt+cpo, which should toggle the cell open/closed, it closes all cells of that type in all open notebooks. If, on the other hand, I type Alt+cp, and then use the mouse to click on Open, all behaves as it should.

These Front End problems are serious and seriously annoying. Sadly, it means I have to drop back to Mathematica 9.

Anyone else have these problems?

All of this is done by hand in a NumberedEquation cell, i.e. it is not output, but straight typing. I typed, for example, x followed by Ctrl+_, which creates the little subscript box, and then typed a;b into that box. If the Cell is not centered, e.g. a Text cell, all is well; however, if the cell is centered or if you center it, then the subscript disappears until I delete the "b" in "a;b".

(2) and (3) I duplicated with Mathematica 10.0.1 on Windows 7. For (3), performing Alt+cpo again opens only the selected cell.
(On Macintosh, I tried (2) and it did nothing.)

I tried (1), using the subscript template from the Basic Math Assistant palette, Typesetting section. Making a subscripted object worked normally. What are the steps you used to try to make a fancy subscript?

"Subscripted variables" are not as simple as they appear to be. If you get to the point where you can make them, using them in executable code is a second, bigger step. See the SubscriptedVariables101.nb notebook linked from conversations http://community.wolfram.com/groups/-/m/t/306808 or http://community.wolfram.com/groups/-/m/t/237039 for more information.
