hi @lidaza

Workarounds (Choose One)

:white_check_mark: Option 1: Delete Explorer Preference File (Recommended)

This fixes the issue for most users:

  1. Close Katalon Studio

  2. Navigate to:

    C:\Program Files\Katalon\Katalon_x64\config\.metadata\.plugins\org.eclipse.core.runtime\.settings

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

  4. Restart Katalon Studio

  5. Test drag-and-drop again

:white_check_mark: 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'))

:white_check_mark: 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 .
