Dave,

 

In HTML code, the presence or absence of a white space before an end tag should not affect the rendering of a document, according to SGML specifications. However, IE sometimes does not get this right.

 

Based on I know CuteEditor doesn't add the white space when editing the content.  Can you paste the original HTML code and the code modified by the CuteEditor?

I will investigate the code and find a solution. 

In the next week, we will release a new build. Please response ASAP.  I hope we can find the answer before the new build.
