Hi Ed!

I am doing a full quote of your message as I CC the new qt-creator mailing list:-)

Yes, this is due to the different instances fighting over the file. Windows insists on locking files that are accessed and that causes those error messages.

You can try to have different settings pathes for all your different instances (use the "-settingspath some/path" argument). That should fix these warnings by having each instance write into its own session files. That will also stop them from screwing up each others sessions:-)
