I have used bzr on linux and would like to start using on windows also. I have some problems. If this is not the best place to ask please tell me. My biggest problem is my coworkers need graphical version trees. The graph-ancestry command from the bzr-tools is not working for me. I have graphviz (latest for Windows) installed and I always get something like this: <div style="margin-left: 40px;">C:\>bzr graph-ancestry cosa.html bzr: ERROR: [Error 32] The process cannot access the file because it is being used by another process: 'c:\\docume~1\\martitza\\locals~1\\temp\\tmpzbup3y\\temp.dot' </div> The other problem is my coworkers are going to need a graphical interface. Earlier versions (six months ago?) of tortoisebzr more or less worked for me but I did not try very hard. Now I have installed the latest 1.13-1 bzr installer for windows, the overlays don't even show. I rebooted twice. Also windows explorer is very slow now. So I believe the shell integration is working, but the overlays are not showing. We might be able to tolerate the slow speed if the overlays worked. Or maybe its slow because the overlays are not working. The tortoise overlays are installed according to the windows add+remove programs. I really want to use bzr and solutions to these questions will make it easier to help my coworkers. Gracias!
