Well here are the help instructions for Point Text in CS3. It seems that the Normal
Enter key and the numeric keypad
Enter key should perform different functions. So its possible the problem is outside of Photoshop
Enter point type
When you enter point type, each line of type is independent—the line expands or shrinks as you edit it, but it doesn’t wrap to the next line. The type you enter appears in a new type layer.
- Select the Horizontal Type tool or the Vertical Type tool .
- Click in the image to set an insertion point for the type. The small line through the I‑beam marks the baseline of the type (the imaginary line on which type rests). For vertical type, the baseline marks the center axis of the characters.
- Select additional type options in the options bar, Character palette, or Paragraph palette.
- Enter the characters. To begin a new line, press Enter (Windows) or Return (Mac OS). Note: You can also transform point type while in edit mode. Hold down the Ctrl (Windows) or Command (Mac OS) key. A bounding box appears around the type. You can grab a handle to scale or skew the type. You can also rotate the bounding box.
- When you finish entering or editing the type, do one of the following:
- Click the Commit button "TICK" in the options bar.
- Press the Enter key on the numeric keypad.
- Press Ctrl+Enter (Windows) or Command+Return (Mac OS).
- Select any tool in the toolbox; click in the Layers, Channels, Paths, Actions, History, or Styles palette; or select any available menu command.
