Hello,

I have recently got a weird crash and the browser just disappeared. This happened several times, on different instances of the same process. The call stack is the following one:

Exception: Child process exited unexpectedly.
== Exception (EO.Internal.jm+e)========
Exception:

Child process exited unexpectedly.

Hi,

This usually happens when you have some third party security/anti-virus program on your machine that incorrectly killed our child process. Make sure you update to the latest build first and see if that resolves the problem, and if that does not help, try to disable the security program and see if it works. If that still does not work, we will need to have access to the system in order to determine the root cause of the problem.

Thanks!

Dragos

This did not occurred anymore. Might have been an accident or something. Keeping an eye on it. Thanks.
