Clipboard problem (Klipper)
 

I use klipper, and often when I save a large amount of text, paste it in a document to save it, it seems to lose its ability to copy anything until a reboot. The next time I will copy text and try to save it, it pasts the first copy instance. I've tried clearing the clipboard history and problem persists. Only happens when copying large files.

Anyone else experience this and know how to fix it?

I haven't experienced this problem myself, but sometimes, when copying large amounts of text, Klipper totally freezes for me, and all I can do to get it working again is killing Klipper and restarting it.
Anyway, have you tried the following?
- Clear Klipper's history
- Close Klipper so it is gone from the system tray
- Start Klipper again from the K-menu entry
