Upgraded to Toad for Data Analysis 2.0 and the Cancel Executing Query button is missing from tool bar.
The button has moved to be the second on the list from the Editor menu now (was the 5th down on the list).
If for some reason if the Cancel Executing Query button has been removed or is missing, please follow the steps below to restore that button:
1. Right-click any blank portion of your toolbar and select "Customize..." at the bottom of the sub-menu.
2. Click on the Commands tab of the new window.
3. Under Categories select Editor and then under Commands, select and drag "Cancel Executing Query" icon over to the Editor menu and drop it in any order desired.
