Frequently Asked Questions

Why does the pen toolbar disappear only in vertical orientation?

This is typically caused by UI scaling conflicts. When the device is rotated vertically, the horizontal screen space is reduced. The application attempts to optimize the display by hiding certain interface elements, which inadvertently causes the pen toolbar to disappear.

Will setting my display scaling to 100% affect other Windows apps?

Yes, changing the Windows display scaling affects the entire operating system. It will make text, desktop icons, and menus smaller across all applications, which might make touch interactions more difficult on smaller screens like the Surface Go.

Can I pin the pen toolbar so it never hides?

While you cannot force the dynamic pen toolbar to stay visible if a scaling bug hides it, you can add specific drawing tools directly to your Quick Access Toolbar (QAT) at the top of the window by right-clicking the tools and selecting 'Add to Quick Access Toolbar'.
