Bug fixes and Improvements v8.1.7378 - 13th February 2023

Disk Images
Some customers have reported a slower backup speed to mechanical HDD. This has been improved.
Incorrect transfer rates were reported for split file backups where automatic file verification was enabled. This has been resolved.
Images could fail with 'unknown error' if the CPU priority slider was at the lowest or second to lowest setting. This has been resolved.
When restoring partition(s) to an MBR disk with logical partition(s) at the front of the disk, the extended partition could be incorrectly extended to beyond the start of the next primary partition. This has been resolved.

Server Plus
ESENT.dll could cause a program exception when Reflect starts. This has been resolved.
