If you're not able to drag-and-drop when using Chrome on a SMART Board (or other interactive whiteboard) or touchscreen laptop, then you may need to enable Chrome's Touch Events API. Here's how:
- In Chrome, enter chrome://flags in the address bar.
- Scroll down to the Touch Events API (or Touch initiated drag and drop) setting.
- Select Enabled in the drop-down menu.
- Restart Chrome.
