Trouble Placing Guides with Wacom Tablet in Illustrator

@Scott28638984nprc you are correct, placing guides in Illustrator with a Wacom tablet can be tricky because the act of lifting the pen can cause the guide to move slightly, a common issue with working on a tablet! I like to double-click on the ruler where you want to place the guide. This often places the guide more precisely than a drag-and-drop motion, and since you're not dragging, the pen lift issue is avoided. Holding the Shift key while double-clicking can also snap the guide to the nearest ruler increment.
