I am having a problem where when you grade the essays, while in the session, you can identify which ones are graded and which are not because the color changes (of course through the css visited property). However, when you close the session even though you do not empty cookies etc. the visited links for the graded essays clears out i.e. goes back to the default. This seems to happen only on the lesson module. The links on the main course page seem fine turning to visited color.
Any idea anyone on how to correct this. There are a bunch of faculty that have identified this issue and would be nice to fix it.
