Error #101: UI.Vision RPA is not connected to a browser tab

[2_05]

Has been mentioned before, but developers were not able to recreate it so far. I’ve found a way to consistently recreate it on my computer.
Command: selectWindow | tab=0
Error #101: UI.Vision RPA is not connected to a browser tab

Steps:
I have the Firefox browser open and several tabs
I have UI.Vision open
I go to CSV and open the CSV editor on one of my CSV files (it opens in a new Firefox window)
I close the CSV Editor
Now when I run my script I get the error
I go to Firefox and switch to a different tab
Now when I run my scripts it works

Hope this helps.

If I remove the pause in the script the error com…

Starting Browser and UI.Vision

Every now and then when I start UI.Vision via API, Firefox displays “Starting Browser and UI.Vision…” but stops at that. Anyone any idea what caused this, or what tweaks I can make to minimize such occurrences?
