I accidentally tried to open a pdf in InDesign that was password-protected. I have no idea with the password is and it will NOT let me "cancel" . I cannot open any files until this dialog box is gone. I tried shutting the program down, but it popped right up when it re-opened. Thanks!
have you tried pressing the escape key?
RANT - I have never seen InDesign respect an escape key.
In 10 years with ID, I have had plenty of instances to back out of a dialog...I don't think the escape key is honored in any of them.
Never having had this particular problem, I don't know that it works for this, but it definitely works to get rid of a loaded cursor, so I though t it might be worth the shot.
