Well, I have my Hot List set up to view priority 3 and events 14 days into the future. This worked in the past but now It wont show any of these events. Today I checked it again and it shows 2 events are hidden due to filters, and I believe that I have all the filters turned off, so it should show? I haven't changed any settings since last time they worked.
Are you sure that you have tasks that match those criteria? I just checked any the hotlist appears to be working correctly. If you have a filter, like a context filter that is blocking the tasks, you could turn the filter off in the filter toolbar.
