I have a coded UI Test that was working fine running locally in debug mode, and randomly just stopped. It still works on other dev pc's but no longer on my PC.
I don't appear to have received any Windows updates or VS updates from when it worked and didn't . What its now doing is clicking the incorrect menu item or not finding a button to click even though its present. The mappings are correct and do work on other machines and its not a timing issue as valid waits are in place and as i said it is working fine on other machines.
Visual Studio Version 15.8.6 Enterprise 2017
Internet Explorer 11.0.90
The exception on the output where it doesn't work seems to indicate an exception with zoom, but the test shouldn't be trying to zoom
IEDOM : ZoomPercentage: Exception when trying to get zoom
The debug output from when it works is as follows
