hi @lidaza

can you share with us which Katalon v11.3.0? the `v11.3.0` or `v11.3.0 - Copilot`?

## Workarounds (Choose One)

## ✅ Option 1: Delete Explorer Preference File (Recommended)

This fixes the issue for most users:

1. Close Katalon Studio

2. Navigate to:

3. Delete the file: `com.kms.katalon.composer.explorer.prefs`

4. Restart Katalon Studio

5. Test drag-and-drop again

## ✅ Option 2: Manually Type `findTestObject()` (Quick Alternative)

If you don’t want to delete files, just copy-paste the object reference:

_`// Instead of dragging, type:`_  
`WebUI.click(findTestObject('Object Repository/Login/Btn_login'))`

_`// Or for API:`_  
**`def`** ` response = WS.sendRequest(findTestObject('Object Repository/LoginRequest'))`

## ✅ Option 3: Check “Link the Selected Part” Setting

Sometimes the Tests Explorer setting blocks drag-and-drop:

1. Open **Tests Explorer**

2. Look for **“Link the selected part”** checkbox

3. Make sure it’s **checked** (not unchecked)

4. Try dragging again

## Why This Happens

This is a **Eclipse platform regression** in Katalon’s underlying IDE components. The drag-and-drop handler in Script Mode isn’t properly registered, so the insertion fails silently

* * *

**Quick fix right now:** Use **Option 1** (delete the prefs file) — it’s the only workaround that actually restores drag-and-drop functionality permanently .
