forcemerge 16728 16752 thanks > Evaluating this expression returns: > (list deactivate-mark > (pp-to-string '1) > deactivate-mark) deactivate-mark is a global variable and lots of functions happen to work on internal buffers, which ends up "unwittingly" setting deactivate-mark to t. There are 2 directions to try and fix it: 1- let-bind deactivate-mark in functions like pp-to-string so as to eliminate those spurious deactivations. But there can be many of them, and it doesn't solve the problem where the buffer-modification is done in a non-temporary buffer. 2- make deactivate-mark buffer-local. This is "The Right Way" but might introduce new problems. E.g. we really should deactivate the mark in all the buffers that have their deactivate-mark set. Stefan
