in version 6.4.3, when using the doc switcher, open multiple documents in notepad++. view any document. right-click on any document in the doc switcher except of the one you are viewing. click close. the document you are viewing will close instead of the one you right-clicked on. notepad++ is acting on the currently viewed document instead of the selected document, which is incorrect behavior. this also occurs for other right-click actions such as "full file path to clipboard".
i believe this is a bug new to version 6.4.3 because i did not notice it in previous versions, and i would have noticed it.
