Calendar reminder alarm, no way to dismiss

[kaiguy]

First time this has happened to me so far. Today I got the typical "alarm" chime for a calendar reminder. But, unfortunately, there was no way to snooze or dismiss it as normal. So every minute or two, I'd get the chime. I ended up having to soft reset the phone to get it to shut up!

Has this happened to any of you? Do you know how to prevent/fix it in the future? Could it be S2U2 causing this problem? Aside from that program, is a pretty vanilla device (only non-standard today plugin is TodayAgenda).

Thanks in advance!
