Sorry about the lack of clarity.
I am opening a 'csv' document in Writer.
When using "Find and Replace" with "Regular Expression" checked and "Search for" using characters "^.".
I click on <Find Next> button. With cursor on position 1,1 of document, it finds and highlights the first position character.
The misbehavior begins now. Clicking on the <Find Next> button increments to the next character, not the next line 1st position.
I have also discovered that if I "Find and Replace" with "Regular Expression" checked and "Search for" using characters "^." but have "Backwards" checked, it works correctly. That is to say it goes to the last line in the document, and repeated clicking on <Find Next> button goes to and highlights the line above at the first character.
I did download "Alternative Find & Replace for Writer v1.4 12/2013". It should not effect the standard "Find and Replace". It also behaves as described above.
The last version it was working in correctly was probably 4.3, but I really don't know.
Away till Monday, so cannot reply till then.
Thanks
