Garmin Haywire Since 30.18

My 1050 has been pretty stable over the last few updates.  However since 30.18 it's developed a mind of it's own.  The bell has been going off randomly with multiple rings, random lock ups, random shut downs, hazard warnings I can't switch off on a ride (without a reboot) even though all hazard warnings are switched off in the Alerts/Prompts menu, individual fields on various screens deciding to change themselves, new workouts not syncing from Training Peaks even though they have synced with Garmin Connect.  Apart from that it's fine :-)  Hopefully it will sort itself out with new updates.  Anyone else having anything similar ?
