Cannot paste text into Find field.
Steps to reproduce:
1) Select some text and copy (from Writer or elsewhere)
2) Use Edit > Find or Command F to get to Find field
3) Paste text: even with field selected, it pasts into document
4) Right-clicking does not even offer a menu
This is NOT the case with the Linux version. There you can paste text and the contextual menu works.
