you probably has some weird status in the progress bar. you can try: SystemProgressMorph reset. that will clean the progress bar status.

The repository listing has to be correct, also in its use of naming and URLs. This is a correct one: http://mc.stfx.eu/ZincHTTPComponents/ - note the simple name and relative URL. But such a relative URL can only work if the base URL of the page ends with /. Monticello can work on WebDAV but it is not written specifically for it. Maybe there are others out there who can help you better how to configure your server. You could also have a look at ZnMonticelloServerDelegate, which is an implementation of a very simple Monticello repository server in Pharo. You should be able to understand the simple protocol from that code.

Maybe you were told about oz? http://www.youtube.com/watch?v=9-ARnlGXjL8 It's a bit experimental, but if you can wait, we can sit on wednesday and try to do it together :).

fileout or something similar from crashed image

by Usman Bhatti

Hello, I crashed my image and I had some unsaved code. Now, I know I can go to the changes file but I'm lazy. I am told there is a tool that allows "repairing/rejuvenating" a crashed image to recover .mcz files and I would like to give it a try. Tx Usman
