Admittedly, this is more of a powerpoint question, but you folks in exceltip land are really really smart!

I've embedded an excel workbook in powerpoint in order to display a chart. Here's the problem:

Step1: i open the embedded excel workbook to modify the chart
Step2: after modifying, i close the embedded file to view the powerpoint slide again
Step3: After closing the excel chart, powerpoint automatically resizes and distorts the embedded chart image. I understand that i can go to Format --> Object --> Size to exactly repair the chart dimensions, however i shouldn't have to do that.

Does anyone know how to make powerpoint stop messing with my chart dimensions? I encounter the same problem sometimes with charts created in powerpoint as well.

Thanks for any tips/suggestions!
