PowerPoint: Negative ELevation Causes Graph to Hang PSS ID Number: Q104399 Article last modified on 09-15-1994 PSS database name: POWERPT

3.00 3.00a 3.00b MACINTOSH

The information in this article applies to:
- Microsoft PowerPoint for the Macintosh, versions 3.0, 3.0a, and 3.0b - Microsoft Graph for the Macintosh, version 3.0b


When you use Microsoft Graph, applying a negative elevation to a 3-D Column Graph that contains negative numbers causes the following problems:

  • Your system stops responding (hangs).
  • The graph becomes uneditable.
  • All unsaved changes made before attempting to edit the graph are lost.

Steps to Reproduce Problem

  1. Start Microsoft PowerPoint.
  2. Create a graph with negative numbers.
  3. From the Gallery menu, choose 3-D Column and select #8.
  4. From the Format menu, choose 3-D View.
  5. Change the elevation to a negative number (for example, -1).
  6. From the File menu, choose Exit And Return To Presentation (update when asked).
  7. Double-click the chart.
  8. The system hangs. Press COMMAND+OPTION+ESC and a message appears, asking if you want to force Microsoft Graph to quit.
  9. Click Force Quit.
  10. A message displays the following: Sorry, Microsoft Graph couldn’t be started. Another graph may be open for editing, or system memory mat be too low. Please close other graphs that may be open, or quit other applications to increase system memory.
  11. Choose OK.
  12. A message displays the following: The application ‘unknown’ has unexpectedly quit, because an error of type 4 occurred.
  13. All changes not saved up to this point will be lost and the graph will remain uneditable.


The only graph that causes this to happen is the 3-D Column Graph #8, with at least 1 negative number and a negative elevation.
