More than a month of hard development brings us a new build 547 that should eliminate all of the issues with hidden system memory use. If you had any issues with unmanaged memory in previous versions, please re-test this latest build. Some major changes were made in the product to prepare encryption functionality that also made it more stable.
If there will be no stability issues found in this build then we will release an RC version with encryption included for the last round of testing. Thank you.
