running dude 3.4
I've set up a couple different email notifications
and gone through and set up the different devices with the notifications I want

for some reason i will open up the polling and notifications i don't want will be turned on
I will unchecked it apply it close the window up and reopen it and it will be checked again

It's funny question. The problem is: when you open device properties the mouse cursor is over the e-mail notification and it if it was unchecked it becomes checked .
Try to resize device properties window or move device in a different place on the map and problem will be solved .
Ones, I had spent about 30 minutes trying to solve the same "problem"

i just spent 20 minutes figuring out what was going wrong for i was experiencing this exact behaviour. this problem still occurs in the dude 3.6.! thank you, gsandul... your hint works perfectly! although this is a mistake that quickly should be fixed...
