**Blender Version**
Broken: 2.74 RC2
**Short description of error**
While drawing with grease pencil and "Continuous drawing" enable the mouse cursor represents a brush, but the cursors resets to the arrow after scrolling with middle mouse button on another panel.
**Exact steps for others to reproduce the error**
1. In 3D vieport, go to "Grease Pencil" in "tools shelf".
2. Activate "Continuous drawing" and press the "draw" button, draw something (the cursor should becom a brush).
3. Go to any other panel/window of blender, like "outliner" or "properties".
4. Scroll holding down the middle mouse button (not scrolling with the wheel).
5. The cursor turns back as an arrow but it is possible to keep drawing.
Not a big deal, can be confusing because blender is still in "drawing mode" but the cursor does not represent such state.
