NotePad++ v6.5.2 installed using unzip of binary zip file
Encoding -> Unicode without BOM
Link Parsing Disabled
Use mouse to highlight a long line of text having links as well
CTRL-C works to copy the highlighted text
Richt-Click mouse on highlighted text copies only last text fragment in it and not the whole of the highlighted text.
When Encoding -> ANSI is used, this problem does not occur.
I'm on windows 7 64 bit using Notepad++ 6.5.2 and I am seeing the same issue.
What I see is if the selected section is 100% spelled correctly it works fine with the mouse. If the spell checker does not like the work the mouse selection falls on this it only takes a few characters. I've tested this by selecting the same string of works in reverse order ( right to left not left to right ) and it works because the last word selected was OK. If it is a non word, I can add it to the dictionary and then it works OK. Hope that helps you find out why the spell checking is interfering with the cut and paste.
I could not reproduce the issue. However, I have a significantly different configuration: Win8.1/64 and a clipboard manager (CLCL).
I checked that the expected text was in the manager, and pasted also to vanilla Notepad succesfully.
Are there other such cases around?
Sorry meant to post my findings. It was one of the spell checkers that cause the problem. I had two spell check plugins. Dspellcheck works without issues. The other one has issues. If when I installed Dspellcheck. So for me this is now working OK.
I came to report the exact same issue as it annoys me too
