Hi I am currently writing a report using Lyx1.4.0pre3 and note that the bookmarks frequently get corrupted.
I have tried testing the bookmark when setting it by moving the cursor a few lines away and checking that Ctrl n brings it back to the original position. However, after some minutes of working in other parts of the document I find that I can no longer return to the same position. This used to be a problem prior to 1.3.6 and I wonder if some bug has resurfaced. best regards samar
