Nope if you follow your steps you dont get the bug. So i am guessing it must be something to do with the image being in a table maybe. Anyway I shall rewrite the steps more formally!

 

1. Goto http://cutesoft.net/example/general.aspx

2. Double click the image of the child in the table.

3. Click on border color color picker, then click anywhere else in dialog, i.e. dont choose a color

4. Click cancel.

 

I can still recreate it using these steps. 

 

Let me know how it goes.

 

thanks
