I was just filling a false positive/suspicious sample report when i came across this quite annoying bug. If you want to fill in the e-mail address for false positive submission, you can't because as soon as you try to use @ symbol in the "Your e-mail address" field, the typing cursor jumps into the "Program version" field. I've tried this several times now and it does it every single time.
Click into the "Your e-mail address" and press "AltGr+V" to create @ and it will jump into the "Program version" field by itself. Only way to do it is to type down @ somewhere else and then copy&paste it into that field. Which is very annoying.
I haven't checked avast! 2015 Beta2 because i'm currently not using it anymore on my systems, but it would be worth checking this there as well, because i don't think it got fixed...
I'm using Win8.1 Update 1 64bit and avast! 9.0.2021.
