The Mystery

After uninstalling StartAllBack, I noticed a persistent UI bug on Windows 11:

• Clicking “Show hidden icons” in the taskbar would open the flyout in the center of the screen, not above the taskbar.
• Clicking “Show downloads” in Microsoft Edge did the same—center of screen, completely out of place.

At first, I blamed StartAllBack. It seemed logical—after all, it modifies taskbar behavior and flyout positioning. I even reset my entire Windows 11 install to eliminate lingering effects.

But the bug persisted. Even on a fresh install.

The Real Culprit

After methodical testing, I discovered the true cause:

The issue was triggered by a third-party utility called Window Centering Helper 1.2.11 Created by Kamil Szymborski

This tool forcibly centers all newly opened windows—including system flyouts that were never meant to be centered. That includes:

• Taskbar flyouts (e.g. “Show hidden icons”)
• Edge UI elements (e.g. “Show downloads”)
• Edge text correction/suggestion
• Many other system popups and notifications

The Fix (or Trade-Off)

If you’re using Window Centering Helper, this behavior is expected. It’s not a bug in Windows or StartAllBack—it’s a side effect of the tool’s logic.

✅ Option 1: Uninstall or Disable the Tool

If you want normal flyout behavior restored: In Window Centering Helper settings (select it from taskbar icons), under “Services” (window will be centered automatically), set the switch to off. Or remove or disable Window Centering Helper.

✅ Option 2: Accept the Trade-Off

Personally, I chose to keep the tool. The benefit of centered windows outweighs the misplaced flyouts—now that I know my system isn’t broken.

Why This Matters

This kind of bug can easily be misattributed. Many users might:

• Blame StartAllBack or Windows itself
• Reset their system unnecessarily
• Waste time chasing phantom registry issues

By identifying the true cause, we save time, preserve system integrity, and maintain trust in our tools.

For MegaHost Users

If you’re building branded CLI tools or auditing desktop UX, consider adding a “Flyout Position Check” to your diagnostics. You could even log known modifiers like Window Centering Helper and warn users about side effects.

Final Thought

Sometimes the bug isn’t where you expect. Sometimes the system isn’t broken—it’s just being reshaped by a tool you forgot was running. And sometimes, clarity comes not from uninstalling, but from understanding. I hope I’ve saved you the time from having to reset Windows. I had this issue on the desktop and on laptop and now it’s finally resolved.

Stay resilient. Stay curious. —Sasa
