Your system hanging is very abnormal. How much RAM do you have now? The tool usually consumes around 200-400MB of memory depending on the size of your test. The storyboard images for the test currently loaded use most of that memory. Could you try it on another machine and see if it behaves better?
What type of application are you testing? Is it Silverlight or HTML based? Could you clarify what you mean by "my playback not recognizing the fact that I've entered text in my User Name field"? What is the symptom? Do you not see the text being entered during playback? Or do you get some sort of a login error? What sort of test step is entering the text? Is it a SetText step or something difference? Could you send us a copy of your test you're having trouble with and point out the step number that is giving your trouble?
Some web applications require you to tab out of the text field before the app will recognize the text has been entered. When the input field loses focus it fires an internal event which causes them to perform input validation on the data. If this validation doesn't occur the app behaves like nothing was entered even though you can visually see data in the textbox. Does your website use jQuery? We don't normally fire the jQuery onchange event, but we can show you how in a coded step if this is what you're dealing with.
The more you describe the symptoms you are getting, and include actual test logs the better we can assist you with overcoming these problems. Is there anyway we can get direct access to your application? Then we'll be able to study the problems you are dealing with and provide direct and proven solutions for you.
