I am using TopStyle 3.5 as the External CSS Editor for Dreamweaver.  When I open any CSS file within TopStyle, I get a popup window that says “File Download – Security Warning” “Open, Save or Cancel?” for a filed called _ts3tmp.asp, after clicking open, the file is opened in Dreamweaver.  I can see by the contents that it is a copy of a webpage I was working on.  It does not matter which CSS file I open the same popup appears and the same contents can be seen in Dreamweaver.   Each time I click the save file icon within TopStyle, the message pops up again.

How can I get rid of this popup message?
