Has anyone experienced the disappearing Internet Explorer (browser) window while executing a fex via the run button in Dev Studio on a machine running Vista? The run button may work properly once, or even a number of times until the browser disappears instead of displaying the expected results (the HTML output from the fex). Iexplore.exe is still listed as a task manager process. Then after the iexplore.exe process is ended (via: end process tree) the run button will work at least once.
This is experienced on my laptop running WF DevStudio 764 stand-alone with Output to PDF, Exl2k, HTML, whatever.
