Hello,
Various issue that I'd suggest you to change/try:
– to isolate the issue please use the qListForm on a clean page (no other web parts on that page)
– try the following scenario
a. create a page called EditPage, add a qListForm on the page, set the site url and the list name, then set the tye to EditListItem
b. from the list view define a LinKTo attribute and make it the following: <yourUrl>EditPage.aspx?ID=<%ID%> (don't hardode any ID)
c. open this page in a new window so you see the ID that is being passed to the qListForm
For more details about using ID or LID please check the above reply.
PS
for the rich text editor customization please open ezEdit and go to Control Appearance tab then Rich Text Editor property.
