"Not enough system resources to display correctly" error
 

I get this error message when I ran my excel application with 10 charts (each
in its own worksheet) which are continually updating with DDE link.
I'm running Excel in Windows XP Personal Edition with the Pentium processor
running around 1.2 GHz with 512MB of memory.
Can somebody tell me what's wrong ? Do I need more memory ?
Thank you very much.
