I write a textbook and therefore I need copy parts of program into Word document. I work in NetBeans, Word, jEdit, PSPad and some other programs in parallel. Once upon a time NetBeans' clipboard losses its contact with the system clipboard. I can use the clipboard inside NetBeans as well as the one inside Windows, but each clipboard contains different text. NetBeans has clipboard of its own, other applications share the system's one.
Restart of NetBeans corrects the behavior and both clipboards for some time again cooperate.
Product Version = NetBeans IDE 7.1 (Build 201112071828)
Operating System = Windows 7 version 6.1 running on amd64
Java; VM; Vendor = 1.7.0_02
Runtime = Java HotSpot(TM) 64-Bit Server VM 22.0-b10
