Thanks a lot. I didn't know about the new feature. Mark

Since the cursor in the first window was positioned on the "u" and in the second window it was positioned on the "j", compare-windows should have beeped and stopped without moving either cursor. Yet, much to my surprise, the cursor (shown below as a '^') in the first window advanced to: uarg=-Ujdbc:odbc:PLDBKSM-20120620 #uarg=-U^jdbc:odbc:PLDBMartin-20120124 and in the second window it advanced to: jdbcURL=^jdbc:odbc:PLDBKSM-20120620 This doesn't make any sense. Furthermore, since I still have 21.3.1 installed, I tried the same thing in the old version, and it behaved as I expected - i.e. compare-windows beeped without moving either cursor.Didn't it also display the chunk between "j" and the cursor in some non-default background color? This shows you where the synchronization point is, and the text that is different between the two windows. IOW, this is a new feature, see the variable compare-windows-sync. If you dislike this behavior, set that variable to nil, and you will get the old behavior. This change was announced in NEWS of Emacs 22.1: *** M-x compare-windows now can automatically skip non-matching text to resync points in both windows.
