Hi Adam,

My clients run into the same problem (since version 6.xx has been installed) and I can reproduce it with Word 2003 and Word 2010 (I haven't tried other versions yet).

The best way to reproduce it is to open a new empty Word document. Paste or type this content into it:

One two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen twenty twenty-one twenty-two twenty-three twenty-four twenty-five twenty-six twenty-seven twenty-eight twenty-nine thirty!

Select and copy the above content from Word.  Then open a new incognito window in Internet Explorer (ctrl-shft-P), this simulates a first time visit to the page containing the CuteSoft editor.

Open the demo of the CuteSoft WYSIWYG-editor for .Net on http://cutesoft.net/ i.e.: http://cutesoft.net/example/general.aspx

Select all content in the editor and delete it. Press ctrl-v to paste the contents of the clipboard.

The result will be like this:

One twothree four five six seven eight nine ten eleven twelve thirteen fourteenfifteen sixteen seventeen eighteen nineteen twenty twenty-one twenty-twotwenty-three twenty-four twenty-five twenty-six twenty-seven twenty-eighttwenty-nine thirty!

As you can see, some of the words have been concatenated, which is unwanted behaviour.

I hope this helps you fix it! Note: after pasting with one of the Paste-buttons, the paste function worked properly, even with ctrl-v...
