[vbox-dev] Clipboard "receiver" program stuck when sometimes

[Aaron Lewis]

Hi,

Sometimes when I copy a text out of a Windows XP guest machine, to an
application running on the host, the host program that receives the
clipboard stuck.

And after a while, it receives nothing. That happens to more than one
application.

It's obviously a problem with VirtualBox, how should I debug it?

P.S Running VBox 4.3+

You didn't mention what host operating system you are using, which is
relevant as we use different clipboard code for each. Are you sure
though that it is not the clipboard code in the guest which is blocking?
You can test this by terminating and restarting (e.g. pressing Win+R
and entering "VBoxTray") the process "VBoxTray" in the guest system.

Michael

Hi Michael,

The host OS is Arch Linux.

And yes, the key combination works, the guest is reset, so it's a not
a guest problem.

And this problem is only happening occasionally

Hello Aaron,

You might want to enable clipboard logging on the host - set
VBOX_RELEASE_LOG=+clipboard.e.l.f in the environment when you run the
virtual machine and you should see lots of additional lines in the
machine log file.

Regards,

Michael
