Reboot your skill : Robot Path - Sometimes Excel instance remains open

Hello,

I am new to UiPath and started learning by leveraging Reboot your skills program.

I created the Robot Path transaction bot in “Understand what you can automate” topic and it is running fine. Sometimes, after closing the “Robot Path.xlsx” file, robot leaves a blank instance of excel on my machine and I have manually closed that.

Anyone else seeing this behaviour?

Thanks,
Adi
