I recently upgraded to 2010.1 and am now experiencing an issue where all day events are causing the day box to grow in height. This is causing greater issues as I have a nightly task that prints calendars. With the size increasing, it is causing the calendar to have scroll bars, and when printed...the scroll bars are obviously of no use to the user, and they can't see the last week of the month on paper.
Anything that changed was strictly due to the upgrade, as I have made no other adjustments.
Help!
I see the same issue in 10.3 1013 build...tried various .css style settings and cant get the day scroll bars (if needed) when an all day event is present in a day cell. I am considering upgrading from 8.1 and was trying the trial build when I found this issue wondering if it has been addressed in the service update of 10.3 (build 2073)
Try setting EnableMultiDayEventBanner=False
That is what solved it for me.
