Anyone have any idea what to do when numbering equations with the "DisplayFormulaNumbered" style in the Default stylesheet and Mathematica does not display the equation numbers as it should? The problem only happens when I use the Option Inspector to modify the starting equation number in a cell that has this style. For example I wanted to jump from equation number 7 in one cell to equation number 9 (and skip 8). The variable I modified was called "DisplayFormulaNumbered" via the Option Inspector. I wanted to start the numbers at 9, so I set the variable to 8 as Mathematica always starts the numbering at the next number, ie 9 in this case. This equation appears OK, but the problem appears on the next equation number (labeled as 10) in the notebook with this style, and several subsequent numbered cells (it eventually starts displaying correctly after about 1 more cells if I use 8 or another 8 cells if I set the variable to 99, even more if I set the variable to 999), in that the closing parenthesis, sometimes even part of the number itself, is either entirely or almost entirely obscured by the right edge of the cell. You either don't see part of the number or sometimes two small dots that are the left edge of the right parenthesis. The equation number is obviously getting clipped. So the basic question is how does Mathematica really figure out where to place this equation number and how to get it to leave more room than it appears to want to leave so that the right portion of the label is not obscured by the right edge of the cell? I've played around with using different alignments and it makes no difference either. I am guessing that Mathematica is somehow leaving room for what it thinks the number "should be" instead of what it actually is (because I modified the variable for a particular cell (and all subsequent ones as well), but that eventually it figures it out, it just takes some number of cells to do it. I've tried making the window much wider, but it makes no difference in this problem either. Well, just discovered that if you close the notebook and reopen it everything seems fine, so the problem is one that happens only during the time the notebook is open when the equation number has been manually modified, and it "heals" itself when the notebook is closed and saved and then opened again. Does that give a clue perhaps as to what is really happening? Thanks... -Bob
