My version is 17.1.717.3711
The popup window is displayed when clicking the ‘Create new test suite’ button.
After that, I am unable to close the popup window, and it cannot be resized either.
Can you still work within the Toad UI to do other stuff?
e./g. what happens when you minimize or re-size Toad?
At the bottom of the window that shows there is a checkbox for "Don't show this again" and a Continue button. If you click Continue it will close. You can also use ESC to close it. Is the window too large to show completely on your screen? I can see the title bar in your screenshot so I know the top portion is visible, but your screenshot cuts off the bottom of the screen.
The shortcut is covering my entire screen, and I can't zoom out or in to see other options.
But pressing the ESC or ENTER key has already fixed the issue.
Thank you so much~
