Copy-paste functionality stops working after about an hour after each reboot on a Windows 7 64-bit system. Running Google Chrome (with gmail and few other tabs open like Calendar, Reader), MS Outlook (which I don't think has anything to do with the problem — I saw it when outlook was off as well), iTunes (188.8.131.52 if it matters).
Would appreciate hints where and what for to look in a registry, and ideas for possible fix.
That is not an Internet Explorer problem (I don't even run it) — it happens in all applications.
Neither Ctrl-C/Ctrl-V nor context menu right-click Copy-Paste (actually, nothing happens on Copy, so there is nothing in a clipboard to Paste) are working. Drag-and-Drop (where supported) continues working though.
