HTMLB was not supported IE-8 and Higher versions for JSPDynPage Implementation.

Dear Experts,

I am using the JSPDynPage concept for custom logon page Implementation in 7.4 SP-12,and Some other pages.But my issue was Document mode in IE.Here this was setting default IE-5.But i need to use latest version/OS based IE version.IE version was higher also it is taking only  IE-5(default).After some R&D i am able to changed the default version.But now some js files are not working.Those files are

1.sapUrMapi_ie6.js

   ERROR: Unable to get property 'createRange' of undefind or null reference.

2.controls_ie5_js

     ERROR: Object doen't support property or method 'all'

And displaying the page left top cornier  small icon after css values changed though F12. Submit Query button visible .

<input name="htmlb_submit" tabIndex="-1" onclick="return htmlbCheckSubmit('id');" type="submit" value="Submit Query">

After logon page on-enter and on-click functions are not working.

Please tell me the suggestions.

Thanks and Best Regards,
