I am confident that Scott's identification of 02847641 as the culprit is correct. That forces a re-read of all BibTeX files on every undo or redo. How long that takes will depend upon how big the files are, how fast the disk access is, etc. I propose to revert that commit in all branches pending a better solution. I don't think that will be too difficult to find. It's just a matter of doing the work. Richard
