title: Can not delete Command Button from worksheet without Excel crashing
body: <p>I have a worksheet that I want to delete.  Originally it contained 3830 rows.  When trying to delete the worksheet, Excel would crash, and completely close.  I thought this might be due to the amount of data on the worksheet, and the presence of a formula in one of the columns.  So I removed the formula from the column in sections, and then deleted rows in blocks, saving each time.  I removed the data until there were only 30 rows left, and still could not delete the worksheet without a crash.  After this I went through the VBA and removed any references to the sheet, in case there was some kind of dependency problem.  This still did not allow me to delete the worksheet.</p>
  
  <p>As well as the data there is a Command Button embedded in the worksheet, which I have determined is the cause of the problem.  The button has no related click event - clicking on it appears to do nothing.  </p>
  
  <p>To modify the button I have to enable Design Mode, which I presume is because it is an Active X control.  If I try to cut the button via the Right click option, Excel crashes.  If I try to delete the button by selecting it and hitting the delete key, Excel crashes.  The button is called 'Sort' instead of 'Command Button 1' or similar, but I have not been able to find a reference to this name in the Name Manager.</p>
  
  <p>I have been through the object properties, and can Edit the Command Button Object, moving the object, resizing it, etc.  I have also been through Format Control, but with no success. Originally the object was locked, but the worksheet was not.  I have unlocked the object, but again this has made no difference.</p>
  
  <p>I have also created a new Active X Command Button and a Form Controls Command Button on the worksheet, and have been able to delete both without any problem.  The workbook in question contains a lot of worksheets so ideally I want to be able to resolve this issue without needing to copy each of the worksheets I want to keep to a new workbook, or a similar fix.</p>
  
  <p>Any suggestions would be gratefully received!</p>
