I started using Selenium IDE yesterday. Everything worked well when I executed test cases on some random web sites, but as soon as I start executing test cases on the business software (of the company that I work in), it fails during the process. Test passes until it comes to the point were I want to verify the Text on the web page (I select any text on the page, click the right mouse button and choose option "verifyText css=h3 selectedtext"). It reports the following error in the Log:
[error] Window does not exist. If this looks like a Selenium bug, make sure to read http://seleniumhq.org/docs/02_selenium_ide.html#alerts-popups-and-multiple-windows for potential workarounds.
If anyone is willing to help me understand this, please have in mind that I am not a developer.
