I was shopping for flights and I could get an itinerary to come up, but if I clicked on "edit search," changed the search parameters, and then tried to select one of the new flights that appeared, I just got an error message. The only work around was to log out and back in and then to enter the new search parameters. I lost count of how many times I had to log out and back in during my flight searching.

I've been encountering this problem for at least several days now.
