during debug step by step, if I click F10 key the forground window remains on the AUT instead of going back
to the UFT. I f I need to click 5 times on The F10 then I need to also click 5 times on The UFT taskbar icon.
I have windows 8.1
From your description it looks like the AUT is on focus when you press F10. Could it be that when you press the F10 it takes it likes a command addressed to the AUT? That could be the reason why UFT is not coming to focus.
Would you please try to see if the same behavior will be reproduced with the Calculator as an AUT and may you please share your observation please.
Thank you and kind regards,
