IDE highlighting the incorrect line

On one project, the IDE insists on highlighting the incorrect line for different conditions. For example, when a syntax error is highlighted, the line above the error is highlighted or when I set breakpoints by choosing a blue dot in the gutter, it does not "line up" with the text line. How can I fix this?

This condition is usually caused by opening the file in a different editor than the editor provided by the IDE. If a line of code is somehow modified and then saved back to the disk using only a carriage return for a line terminating character (instead of a carriage return + line feed sequence), the IDE may get confused. To fix the problem, load the file into an editor that will save each line with a carriage return + line feed sequence.
