1. Track MSAA location changed events for caret (easily done with MSAA inspect tool)
2. Open data:text/html,<form><input type="text" name="zzz"><input type="submit"></form>
3. Tab into text field and see caret position highlighted with yellow triangles
4. Move window around

The farther the window moves to the right, the more the extra horizontal offset increases.
Also, the farther the window moves down, the more the extra vertical offset increases.

This affects ZoomText.
 

1. Ensure scaling is on for Windows (under Display settings, "Change the size of text, apps and other items" -- set to 125% or larger.
2. Track MSAA location changed events for caret (easily done with MSAA inspect tool)
3. Open data:text/html,<form><input type="text" name="zzz"><input type="submit"></form>
4. Tab into text field and see caret position highlighted with yellow triangles
5. Move window around

The farther the window moves to the right, the more the extra horizontal offset increases.
Also, the farther the window moves down, the more the extra vertical offset increases.

Steps (example using caret):
1. Ensure scaling is on for Windows (under Display settings, "Change the size of text, apps and other items" -- set to 125% or larger.
2. Track MSAA location changed events for caret (easily done with MSAA inspect tool)

5. Move window around

The farther the window moves to the right, the more the extra horizontal offset increases.
Also, the farther the window moves down, the more the extra vertical offset increases.

The same bug occurs for accLocation on non-caret objects as well.

This affects ZoomText. Many systems have scaling set by default.
