Placing cursor focus in the 'To:' field ready to type in Notes

On my previous version of Notes, when I opened a new email with an attachment, the cursor focus was placed immediately in the ‘To:’ field ready to type.

This is still the case with a new email but not so when I open a new message with an attachment.

I’m now working on Notes 6.5.3

Is there a simple cure for this please?
