title: In Builder, why can't Beyond Compare open the temp file associated with the buffer
body: <p>I am using C++ Builder XE3.</p>
  
  <p>Most of the time, the Beyond Compare utility embedded in XE3 works without any problems, but it gets into a mode where it can't open the temp file associated with the buffer. It shows the "File Not Found" message, then the path to the temp file.</p>
  
  <p>It will work if I save the file, but as soon as I make any changes, it gets lost again. Shutting down Builder and cleaning out the temp directory is of no help.</p>
  
  <p>Any ideas how to stop this random like behavior.</p>
