  I am using the RadColorPicker in an asp.net repeater control.
Everything works well except that the browser (any browser) is consuming approximately 500MB of memory 
with only 13 items loaded into the repeater.
If I comment out the radcolorpicker, memory consumption drops to around 60-70MB...  which is a little 
more appropriate.

Memory usage is the same regardless of whether or not I handle the OnClientColorChange event, so I'm 
pretty sure that whatever is going in is happening as a part the control's default behavior.  

I am using the latest available controls.

Are there any known issues with this control and memory leaks/consumption?

Thanks...

  Hi Joshua,
  
    After extended testing in the major browsers on the market today, i.e. IE, Firefox, Chrome, Opera and Safari. I couldn't reproduce the issue that you are reporting. The only browser that performed a bit worse was the newest version of Firefox, but the memory consumption didn't go very high altogether. With the other browsers the memory usage varied in a range from around 2-3 MB.
  Still we will observe more closely the behavior of the ColorPicker in various scenarios.
  
  Thank you for your active involvement in this matter.
  
  Kind regards,
  Niko
