Dear Mr. Kiran,
We are experiencing the same problem. I work together with seven other colleagues in the publications department of a scientific research centre that regularly publishes scientific reference works (containing numerous formulas). Since we have strict deadlines and a lot of documents are affected by this problem, we hope that Adobe is looking for a more permanent user-friendly solution, instead of the temporary bug fix to revert to older ID versions. Saving the formulas in other file formats (.eps, .jpg, .tif, .ai, etc.), is not an option as the print quality is insufficient. Can you keep us posted on your progress and let us when we can expect a solution?
