Hi Kelly,
Just love the product line up you have with the events calender, still lacking in places(namely recuring tickets with user details collection) but that should hopefully be sorted soon.
Just wondering when the next scheduled maintenance release will be to fix this problem as my client as also run into this. They have also noticed events dropping from the current month if they hit a certain number of events as well. We have currently changed it to display in list mode. But they really want the monthly calender view in asap.
Btw during my poking around in the sql code (before i saw this post and notice you said it was in the html generation side) i did notice that the sql return for the monthly view with recurring events does not filter out events before and after the month being queried.
