title: Excel workbook not responding
body: <p>I am using Excel 2010 and am having difficulty with one old workbook created in Excel 2003. Lots of symptoms to report!</p>
  
  <p>No other workbooks are giving me this problem. This problem file usually causes "MS Excel - (workbook name.xls) [Compatibility Mode] (Not responding) and a blank screen apart from the task bar and this Excel message on a single line across the top of the screen. Waiting doesn't solve the problem. If I close Excel and choose the "Close program" option, it sometimes shows me the file as I remember it for a couple of seconds, then the program closes. Re-opening the file just gives the same behaviour again. During the first few seconds of loading, I can see the message "Contacting server for information" at the bottom of the Excel screen. </p>
  
  <p>In Task Manager I can find EXCEL.EXE *32 running. I'm using Windows 7 Pro 64 bit. </p>
  
  <p>This is a file I use regularly in projects as a specialised calculator, and so I re-copy it each time and save it to save the calculation records in the project file. I've found that versions of the workbook created even several years ago and have given no trouble until now all suffer this problem, so it looks like a problem with Excel 2010. This is the first time I've tried to open these files since migrating from a Win XP computer running Excel 2003.</p>
  
  <p>Please can anyone help me to open the file and to resolve the problem?</p>
  
  <p>Thanks</p>
