Make text in error messages copyable

[Jaydude-wb]

The text in error messages is kind of 'dead'. When we need it to report an issue, its a pain. Please make this text selectable and copyable.

You may already know this, but (at least in Windows) when an error dialog has focus, Ctrl+C will copy the error text to the clipboard. The text in the dialog isn't individually selectable, but you can copy the whole thing this way.

Thanks Dan, I'll try this on MacOS with cmd-C.
