Every WEB LOOKUP search giving me an "Object reference not set to an instance of an object" error

Question

The searches do work, but I have to dismiss this pop-up window every time. 
 It wasn't doing this when I started the project; I believe that some keystrokes meant to navigate the document in Studio 2017 accidentally corresponded to a Studio 2017 keyboard key combination that changed a setting. 
 But I don't know what. 
 Thanks, as always!

I think you were right. I probably opened a tab without realizing it. For other reasons, I restarted the computer and the error is not coming up any more. If I find a search that gives me that error, I'll post it. 
Thanks!

Hi John Narins , 
 
Try changing the weblookup keyboard shortcuts? Look in your keyboard shortcuts and sort by the shortcut. This way you can spot any duplicates fairly easily.
