Keyword Test not working the second time

Hello,

The application I am testing is a web application. I have a Keyword Test that runs successfully the first time but the second time it is always in error. Basically what my test does:

1- Click on the input text field
2- Do a "Ctrl + a"
3- Make a "Delete"
4- Enter new text

What I seem to notice is that the click on my field no longer works after the first time. So the "Ctrl + a" and all the rest either.

What I have tried to try to fix the problem:

1- I validate if my field exists and it returns True
2- I put some "Delay" before each operation but that doesn't change anything

3- I configured "auto-wait" property on operations and that doesn't change anything
4- Add an operation to put the focus on my field before the clic
5- I tried to put several "Click" operation in a row and it doesn't work either

I'm really out of ideas.

Help please!

Thank you.

Katherine
