I am running bzr 2.2 packaged with bzr-explorer for Windows with the same "big" project I've described here before. I have a shared repo at D:/VCS/bzrEval with main branch D:/VCS/bzrEval/trunk and I branch to D:/VCS/bzrEval/dev_d within the shared repo and I get the following message in .bzr.log (and in the bzr-explorer GUI): ImmortalLimbo: Unable to delete transform temporary directory D:/VCS/bzrEval/dev_d/.bzr/checkout/limbo. Please examine D:/VCS/bzrEval/dev_d/.bzr/checkout/limbo to see if it contains any files you wish to keep, and delete it when you are done. [Traceback is attached] It turns out that the limbo directory is empty. But what would I have done if it had files in it? I need to understand this well enough to be able to explain it to people who are just trying to get their (non-bzr) jobs done. I repeated the branching (from /trunk to /dev_e, both in the same shared repo as above) and I did =not= get the ImmortalLimbo message. I will try again with bzr-explorer and see if it does it again, or if this was a one-time thing. Either way, I need to understand how to respond. Thanks ~M
