Hey guys;
I am evaluating (30-day trial license) DF pro.
My main objective is to stop multiple open windows from switching to other monitors when computer sleeps and wakes up.

OS is Windows 10 Pro current build
System is Ryzen 7 3700X
Display: Gigabyte NVIDIA GeForce RTX2070 Super
Monitors:
#1 Asus Tuf Gaming VG27AQL1A @ 2560 x 1440 @ 144Hz on DisplayPort
#2: NEC EA244WMi @ 1920 x 1200 @ 60Hz, on DisplayPort
#3: Samsung 2494HS @ 1920 x 1080 @ 60Hz on HDMI

When I have several windows open on the primary (Asus) monitor and I let the computer sleep (after 20 mins) and restore to Lock Screen, the windows that were open on the primary monitor always move to monitor #3 on HDMI.
I have read that this is a common issue with DP.
This is the primary reason I want to use DisplayFusion Pro.

So I Googled, and found how to set up triggers in DF so that the window positions are saved just before the computer goes to sleep, and then loads when I unlock the computer from the Lock Screen.

Using the advice from my search, I wrote the following triggers:

Triggers tab:
Enable Triggers: Yes

Triggers:

Desktop Unlocked
Order: 1
Stop Processing: False
Frequency: Always
Match Conditions: <null>
Actions: Wait: 5000ms, Run Function 'Restore Windows Positions from last save (Pro only)

System Idle
Order: 1
Stop Processing: False
Frequency: Always
Match Conditions: Idle Timeout (sec): 1140
Actions: Run Function: 'Save Window Positions (Pro only)'

The first time I allowed the computer to go to sleep, and then unlocked, the windows that had been opened on the primary monitor were on the #3 monitor, but after the 5 second 'wait', they moved to the primary monitor where they had been before sleep.

But the next time I let the computer sleep, then unlocked, the windows that were open on the primary monitor were on the E3 monitor and did not restore to the primary monitor after the 5 secs.

So I'm asking whether the method I was given is unreliable, or is there really no reliable method to do what I want to do with DF.

Since this is the primary purpose that DF will perform for me (I also like the feature of preventing the mouse cursor from snagging when moving between mis-aligned monitors, as my monitors are not the same resolution), having a permanent solution to this annoyinw Windows problem is going to determine whether I purchase a license for DF Pro after the 30-day trial.

If DF cannot do this for me, I suppose I will need to wait for Windows 11 to be released, which I understand might fix this problem.

Thanks for your help

Actually, the problem occurred only once or twice. Most other times the triggers work fine. Perhaps there was another app running that caused the problem, but I haven't been able to reproduce it.
