Send Keys Suddenly stopped working in Production Session


I have deployed my solution in production before 3 months and since now Solution was working fine. but from last few days Send Keys suddenly stopped working. I have used Ctrl+f10 to maximize Excel macro file after download. Now BOT used to activate the Excel macro file but unable to work for send key.
If anyone have idea please help me.

Hey @nilesh.mahajan

Maximize window activity could be used for maximizing the window. This could be more promising then send keys method.
