Yes, I’ve tried no less than three themes, and each one was with no other plugins enabled. I did notice however, the error only occurs when you use the enter key to refresh the search. For instance, if you select a taxonomy after changing the keyword, it refreshes the search without the double click afterwards.
The problem only occurs when you use the return key to initiate the keyword search. If you enter the keyword and then click the mouse, then it doesn’t happen.
