This is a minidump from one of the beta builds.
Does it really occur even in the release build? If so, please post the dump from the release build.

Thanks
Vlk

I'll reproduce the problem and send you the latest minidump file created, but it'll be later on in the day (3-6hrs) when the customer has awaken.

.. sorry for the large delay, but I promise I won't forget yea. :)

I guess it has a mind of it's own, .. it'll probably take a couple of days for the problem to show, depending on if the problem still exists with the public release. The minidump I sent was from the previous beta release (4.8.1273), if that makes any difference.

My personal guess is that the crash won't happen anymore with the release build. Let's wait and see though... :)
