We have a strange , intermittent, problem. We make changes to a page and publish the single page. Then make changes to another page and publish that page to the site. We then close NOF and a little later open NOF and try to open the site and it hangs (either no response or NOF just closes). So, assuming something for one of the 2 pages caused the problem, we start up the last successful site from the "Recovery" directory. We then repeat the steps above but close NOF after publishing the first page ,open NOF, make changes to the 2nd page, publish it, and close NOF. We can than open the site successfully. To avoid having to recreate too many changes after such a failure, we now close NOF after making changes and publishing only 2 pages. This is very inefficient. How can we debug this problem or get some insight on what is happening.
