Stack Overflow at line 56?

[silliemillie]

Just been sending some emails when the message 'Stack Overflow at Line 56'
I'm sure you all know what this means but I am rubbish at computers.
Can anyone enlighten me?

I know this is a cliché but I do in fact know roughly what I am talking about, this error could be caused by many different things.

Just shutdown the system fully (i.e. not sleep/hibernate) etc. and switch it back on again.

If after this it keeps happening write back with how you were trying to send emails (browser type, email service, etc.).

Computer stacks are as they say just a stack of memory addresses. Data gets put on the top of the stack and gets removed from the bottom. The terms Push and Pop are often used to describe the process. Obviously in your case the number of empty stack addresses have run out and can't handle any more input.
