I use QTTabBar since qttabbar-v1.5.0.0b2, until I found this site, and I install QTTabBar_1038.
After installing, I found sometimes Ctrl+C and Ctrl+V don't work, unless I press it twice/thrice.
qttabbar-v1.5.0.0b2 doesn't have this problem.
I am using a notebook with Windows 8.1 x64.
I was first suspecting my keyboard. When I disassembled and modded my notebook I folded the flat cable of the keyboard. I thought the cable may be broken.
To prove my opinion I install KeyCastOW to check if Ctrl+C is really pressed. And found out that it IS pressed, and the "copy" step is not working.
I try disabling QTTabBar from the add-in manager, and Ctrl+C works good.
I also try deselected all keyboard shortcuts in the QTTabBar settings but the problem still exists.
Can you help me why this happens and how to avoid it?
Sorry for my poor grammar, hope you understand.
If you have questions please don't hesitate to contact me by e-mail (which I filled above)
Thank you for reading!
