Hi,
Yes, some people did experience a problem with the first builds of version 2.7. The problem would show up depending on other settings in the software, and so it was difficult to detect and track.
Nevertheless, this is fixed in build number 456 and later. Note that the software is still called "2.7" because we only change the version number when there are substantial new additions.
Please download the new version on the web right now.
Best regards,
William Benner
