Hello.

Correct me if I'm wrong but is there a possibility in mIRC options to switch on the option of displaying this window once again?

I've found such an option only in mirc.ini (section [options], n0 position 34) - the value must be manually changed to 1.

I think it's a pity that in mIRC options there is nothing like a single window to configure 'windows warning messages'.

Regards.
