Using Reflect v7.3.5925 after having switched from the Windows Task Scheduler to Macrium Task Scheduler I discovered that the computer does not suspend after having made the backup, if suspend is included in the backup definition. The screen does turn black, but the computer does not go to standby.

To test this further I also made a new backup definition with a new schedule, but it suffers from the same problem. In both cases reverting back to the Windows Task Scheduler solves the issue. Also, starting the backup manually via the Backup Definition Files tab does suspend the computer, even when Macrium Task Scheduler is used.

I cannot trace with which version this issue started, since I only switched to the Macrium Task Scheduler a couple of days ago. Last year I reported another issue where Macrium Task Scheduler woke up the computer a few minutes after having suspended it. I can see in the release notes that it was fixed in v7.3.5672. Unfortunately, I do not recall whether I tested that it solved the issue for me. I did however stay at Windows Task Scheduler. I also found this similar topic, but that topic does not state which v7 was used.

For now I have reverted back (again) to Windows Task Scheduler. I am using Windows 7 x64.
