I can see a reference to a new patch for WWB20, but I can't see where the fix itself can be downloaded or instructions about how to install it.

Still very new to WWB and this forum, so I've probably missed something - apologies in advance, and thank you.

You can always download the latest version here:

Note: In most cases, you don't need to worry about hotfixes.
However, since version 20 is a major new release, we may fine-tune the new features during the first few days after its launch, based on user feedback.
If you do not experience any issues yourself then you can also wait for the official update.

Ah - so you have to reinstall the program. Thanks - this really wasn't at all clear from your post about it yesterday (speaking as a newbie).

Thanks.
