Frequently Asked Questions

Why do shapes suddenly jump to another page in Word for Mac?

Shapes jumping to different pages or locations is often caused by the text wrapping settings or object anchors. Right-click the shape, select 'Wrap Text', and change it to 'In Line with Text' or 'Square' to stabilize its position. Alternatively, lock the object anchor to a specific paragraph.

How do I stop a shape from distorting when I resize it?

To maintain the original proportions of a shape while resizing, hold down the 'Shift' key on your keyboard while dragging the corner handle. You can also right-click the shape, choose 'Size and Position', and check the 'Lock aspect ratio' box.

Can opening my Word document in WPS Office fix layout bugs?

Opening the document in WPS Office bypasses Word-specific rendering bugs. Since WPS Office has exceptional compatibility with .docx files, your document and shapes will load properly, allowing you to edit and arrange them exactly as intended without unexpected scaling issues.

Why does my drawn line reverse direction when I let go of the mouse?

This is a known bug in certain versions of Microsoft Word for Mac where the rendering engine misinterprets the vector coordinates of lines and arrows. Updating to the latest version of Word is the most reliable way to resolve this specific behavior.
