This may or may not be connected to ticket #619. It has similarities, but there are also differences.
Anyway. When shared-clipboard on the guest is set to bi-directional, all clipboard functionality stops working. Both on the guest and the host, at least for text (which is what I use most).
Host-to-guest or guest-to-host works fine, but bi-directional nothing works.
If I set a VM to bi-directional, I can still copy and paste in that VM.
When copying in Windows host, I cannot paste that in windows host or windows guest. After that, I also cannot copy and paste in the guest VM.
Setting shared-clipboard back to any other mode restores functionality. Usually.
Strange thing: 7.2.12 crashed on VMMR0, which crashed the Windows 7 VM so it would not boot. Restored to a restore point to get it to boot again. Then updated to 7.2.14. Since something with unicode clipboard was changed decided to try and on that Windows 7 VM it worked. Tried on the W10 VM and it didn't work. And from that point it also doesn't work on the W7 VM anymore.
VBox.log.1.log is when it somehow worked in the W7 VM (even though it shows errors)

Cannot paste the lines at this moment, as with al the switching to the shared clipboard it isn't working at all in my host windows anymore...
EDIT Added the lines after a reboot so clipboard worked again
Re-installing VirtualBox doesn't help.
How can we reproduce this?
Probably not. As not everybody seems to have this problem. But on my system (and that of a colleague) it works consistently. So I'm willing to test if you need any info.
Did you upload all of your necessary log files, screenshots, etc.?
