GUI Wonky?

When I’m using my iPad to work on mail I’ve noticed this issue for quite sometime now and I mean for over a year or more. The issue is for example if I am composing an email and go to send it the process of tapping “send” doesn’t work because it seems the process of tapping no longer lines up with the underlying “send” function. In this case in order to send the mail I must totally back out of RB7 log back in and then open the mail in the Que, the mail will then launch using the send button. Has anyone had a similar experience?
