A particular html/text module has stopped being editable: The problem started when adding a new page and copying all the modules from this parent page. Now one of the "untouched" parent page's particular html/text module can no longer be edited. You can call up the parent page fine and click on Edit Text within the "problem" module but all you get back is a blank skin where the editor should be. So in our case the problem starts with a copied module to the newly added page (and not done as a reference). So something in the process of adding a new page and copying/referencing a parent page module has caused a html/text module on the parent page to no longer be editable. The child page seems to be fine. Other modules in the parent page (such as link) that were copied to the child page as a reference work OK and can be edited. When creating a new page we tend to copy (one) and reference about 5 to 7 total modules. Clearing cache does not help. Resetting IIS does not make a difference. The log does not indicate anything other than the new page was created. Waiting does not make a difference , yet anyway. It does not appear to be a permission problem only because it does not provide a warning about "Access Denied". You just simply get a blank skin in place of the editor. We have added other new pages and copied things from the parent page earlier with no problem. Thie problem seems so random. No proof at the moment but I have a feeling in our case this is not an isolated hardware problem. Any help would be greatly appreciated.
