I've just had my computer fixed after some nasty virus-induced problems.
So I'm rather nervous about any new pop-ups/messages.
While A2King today I've received a message, which looks like a Microsoft one, saying:
A Runtime Error has occurred. Do you wish to Debug. Yes & no boxes underneath.
My question: What does this mean
And how should I respond to it

Is there any cause for concern

(I've never received this message before)
Any advice will be much appreciated.
Thank you.
