Cursor disappears over editor if leaving selection with eyedrop tool still in use.

In the windows app. I was selecting a color with the eyedrop tool. I left the eyedropper on and selected a different item in the tree. The eyedropper cursor was still visible even thought I no longer had the color selected. I tried changing to the selection cursor but now the cursor is invisible when over the preview window. Oddly, all the drawing tools like the pen tool are still visible but not the selection cursor. This was on Windows.
