Having selected text the selection then crumbles to one word under the cursor after I click the right (context menu) button. Thus I cannot perform any operation on the selected text. I'm sure it can be resolved in the n++ settings but I'm not sure which setting is responsible and should be changed .. any ideas ? thank you.
This is probably because of the spellcheck plugin. Press Alt-A to shut it off (or deselect "Plugins->DSpellCheck->Auto-check document" in the menus).
that was indeed the case. Thanks.
