Hello Madhavisri,
There can be a few causes of the problem:
1. The browser Zoom option is set to a value other than 100%. Make sure that the browser zoom is 100%
2. You obtain an incorrect object in the script (due to using indexes and other unstable recognition parameters). To check if you get the correct object, call the Sys.HighlightObject method from your script just before hovering the menu item. TestComplete will highlight the object with a rectangle. If an incorrect object is highlighted, correct the recognition criteria (either in
Name Mapping, or in your script).
3. If the problem remains, it can be related to specifics of the page you are testing. In this case, we need to reproduce the situation with the problematic page here. Please send us the link to it.
