I have a fairly large workspace. I just did a "find all references" to a highlighted function. The scope was set to "current workspace". That was an error. I really only wanted to search the file. But the cursor went to busy and the application is unresponsive. I should be able to cancel the search. I wouldn't mind waiting if I could do something else, but the app goes "gray" and I can't do anything until it finishes searching.
