Update Drivers and Test in OneNote for the Web

Updating your Wacom drivers and testing the web version helps determine if the issue is a system-level hardware conflict or specific to the desktop app.

Often, a mismatch between a newly updated Windows OS and older peripheral drivers can break specific pen gestures like the long-press to lasso.

1
Update the Wacom Driver

Open the Wacom Desktop Center application and check for any available driver updates. Download and install the latest version for your Wacom Intuos.

2
Check for Windows Updates

Navigate to Windows Settings > Windows Update and install any pending updates for Windows 11.

3
Test OneNote for the Web

Log into OneNote for the web through your browser. Try using the pen's long-press gesture to see if the lasso tool activates, which indicates the hardware works properly.

Frequently Asked Questions

Why does my Wacom pen long-press act as a right-click instead of the lasso tool?

This is often a Windows Ink setting conflict. You can adjust pen behavior in Windows Settings > Bluetooth & devices > Pen & Windows Ink to ensure long-press is configured correctly for your applications.

Can I manually select the lasso tool without the pen shortcut?

Yes, you can manually activate the lasso tool by navigating to the Draw tab on the OneNote ribbon and clicking the Lasso Select icon before dragging over your notes.

Does this pen issue affect all OneNote notebooks?

Typically, input tool issues are application-wide. However, creating a new notebook and testing the pen can help rule out file-specific corruption. If it works in a new notebook, your original file might need to be synced and rebuilt.
