  Hi,
  I had my application running perfectly but now I've got a very odd message regarding the Spell Check. Once I try to check a few textboxes on my form, I now get a popup message saying :
  
  "...Server returned error : 500...
  /<myApp>/RadControls/Spell/Telerik.RadSpellCheckHandler.ashx undefined...
  <title>Object reference not set to an instance of an object.</title>..."
  
  I've got the whole RadControls folder is my web application, which is still using .NET1.x and the .dll version that I'm using is 3.0.2.0. I've tried everything described in the help file and nothing seems to work. Any clues ?
  
  Any help will be appreciated.
  
  Regards,
  
  Cristiano

  Hi Cristiano,
  
  Could you try to register the spellcheck handler in your web.config, as it is described in the following help topic:
  
  Spell Check Handler Configuration
  
  I also recommend registering the dialog handler in web.config:
  
  Dialog Handler Configuration
  
  Another reason for the problem, could be an URLRewriter. To fix the URL rewirter problem exclude the spell dialog from the URL rewriting routine.
  
  If this is not the case, it will be best to open a support ticket and send a small sample project where this error can be reproduced.
  
  Kind regards,
