Comment 2 for bug 1477696

I already mentioned that I'm not using any keyboard or clipboard enhancers (no managers, no any software which controls it).
Antivirus is quite standard - ESET NOD32.
Also - all other software (microsoft office 2010, notepad, etc) perfectly works with clipboard.
Which means - there is bug in Calibre!

Please change status back to Valid bug.
Because it is very serious problem in your software.

Please see - when all other software works fine with clipboard but only Calibre has problem. That precisely means - BUG IS EXACTLY IN CALIBRE.

Please check/review your code which works with clipboard - you may find a bug there.
