Hi, Multihog. This issue, or one very similar to it, has been reported and we have a workaround for it. If you could, please get the latest beta version that we've released and try that. It should address this issue. If it does not, then please let us know as soon as possible.
Thank you very much for your patience.
Here is a link with information on how to get the latest beta version:
