Please follow steps:

 

1.  open link http://cutesoft.net/example/datagrid-example.aspx  in firefox3.6.3

2.  select the first record and then click "Edit"

3.  input " this is a test" in editor area

4.  select "this is a test", and then click button "Insert Hyperlink"

5.  input "http://shop.joomla.org/mens-joomla-sport-shirt.html?ProductID=10917&SizeID=6&Quantity=1&ColorID=2&x=101&y=24" in Url

6.  click "OK"

7.  test this link and check whether it works

 In this scenario , it works in my computer. 

 

Use another way to test it,

1. open link in http://cutesoft.net/example/general.aspx in firefox3.6.3

2. switch to "HTML" view and remove all content

3. switch back to "Normal" and input "this is a test"

4. select "this is a test"

5. click "Insert Hyperlink"

6. input "/test.aspx&id=blabla" in URL

7.click "OK"

8. switch to "HTML" view, and check the produced html code, 

      <div>

         <a href="http://cutesoft.net/test.aspx&amp;id=blabla">
            <div>this is a test</div>
        </a>

     </div>

 

This is a valid html code.
