The QEMU emulator did not enqueue mouse events; it simply records the latest mouse state. Prior to this update, double click or dragging mouse events were sometimes lost, especially on high-latency connections. Now, the code for mouse descriptors has been fixed, and lost mouse events occur much less frequently.

Reproduce the issue on kvm-83-224 Verified the issue on kvm-83-235 steps:( for this case I use the slowest vpn proxy address to test) 1.start win08 guest as followings : eg:/usr/libexec/qemu-kvm -M rhel5.6.0 -m 2048 -smp 4,sockets=4,cores=1,threads=1 -name windows2008_qcow2 -uuid cddeab65-2ded-43db-094a-fd4f8ec2d69f -monitor stdio -localtime -no-kvm-pit-reinjection -boot c -drive file=/home/windows08.qcow2,if=ide,bus=0,unit=0,format=qcow2,cache=none -drive file=/home/en_windows_server_2008_datacenter_enterprise_standard_sp2_x64_dvd_342336.iso,if=ide,media=cdrom,bus=1,unit=0,readonly=on,format=raw -net nic,macaddr=54:52:00:4f:26:51,vlan=0 -net tap,vlan=0 -serial pty -parallel none -usb -usbdevice tablet -vnc :1 -k en-us -balloon none 2.in the guest ,modified the double-click speed to fastest in the control panel. 3,Tried to open some folder or files by using double-click Acutal Results: on kvm-83-224 ,50% times double clicks in the guest does *not* work. on kvm-83-235 ,random times double clicks in the guest does *not* work Based on above ,this issue has been fixed.
