I have opened the AppleScript Editor and pressed Record button.
Then I run TextEdit, create a file and put some text there.
When I click Stop button in AppleScript Editor, nothing was recorded, the window is blank.
What is the problem?
Not all (or even many) applications are recordable -- if the app doesn't jump through the right hoops, nothing you do in it will show up in the recording. This does rather limit the usefulness of AppleScript's recording capability...
