In TestLeft 2.1, the following bugs reported by our customers have been fixed:

Improved performance of the QuerySelectorAll method for test objects in Edge and Chrome.
Fixed: Object coordinates in Edge were calculated incorrectly if the Favorites bar was displayed.

Note: Users need to restart Edge after adding or hiding any toolbars to avoid the issue in the future.
Fixed: TestComplete could not identify JavaScript dialogs (such as Alert) in Chrome on Windows 10.
Fixed: Firefox crashed if the Highlight on Screen command was used in the TestLeft UI Spy panel.
Fixed: The UI Spy’s “Pick Object” tool could not identify web page elements in Firefox in some multi-monitor environments.
Fixed: When testing web pages in Internet Explorer, the FindChildByXPath method sometimes returned a native DOM object instead of a test wrapper for this object.
Fixed: TestLeft stopped identifying web page elements in CEF applications after a few test runs.
Fixed: A slowdown when working with objects identified via the UI Automation engine on Windows 10.
Fixed: TestComplete could not select items in a WPF pop-up menu during the test playback.
