Hi,
Did this problem only appear in specific PowerPoint file or all PowerPoint files?
How about other Office products?What size are problem files?
How did you insert the Table or Worksheet?
If you insert a Worksheet, how large is the embedded Worksheet?
Where did you save the file? In local or network?
I suggest you try to create a new file with table or Worksheet in local desktop, and check if this problem still exists.
You can also try to increase the virtual memory size.
