FancyZones restores child window position to main window position

[W4RH4WK]

Microsoft PowerToys version

0.75.1

Installation method

Microsoft Store

Running as admin

No

Area(s) with issue?

FancyZones

Steps to reproduce

• Tick "Move newly created windows to their last known zone"
• Untick "Allow child windows snapping"
• Start Visual Studio 2022
• Snap main Visual Studio window to a zone
• Drag a tool window outside the main Visual Studio window
• Close Visual Studio
• Start Visual Studio

The detached tool window is placed over the main window by fancy zones

✔️ Expected Behavior

With "Allow child windows snapping" off, FancyZones should not reposition child windows.

With "Allow child windows snapping" on, FancyZones should remember child window positions and correctly restore them on program launch.

❌ Actual Behavior

The child window position is always restored to the main window position, effectively covering the whole main window on program launch.

Other Software

Visual Studio 2022
(probably all Apps featuring child windows)

Could you please check if it's still reproducible on the 0.76 version? /needinfo

Yes, still reproducible with 0.76.

Thank you for checking. I was able to reproduce the problem; it happens only after opening, but when you try to drag the Solution Explorer window, the zones won't be triggered if the Allow child windows is not enabled.
It turned out that the Solution Explorer window appears when the main window is not yet visible, so it's not considered a child window. We'll figure out what we can do to resolve this problem. Thanks.
