Dump while clicking on window in WebDynpro ABAP

Hi Group,

I am facing an issue when I am clicking on window in webdynpro component as refer to the screen shot and this is IDES 6 ehp 5

Earlier I was not facing this dump but for some time I am getting this

Now as per the dump the Jnet Active X is missing so :

I checked and while installing the sap gui 7.20 version I have seleceted the Jnet to be installed .

Still I got this error then I installed sap gui 7.30 version but still I am getting the dump .

Alternatively when I am accessing the other server for webdynpro I am not getting this dump .

Please let me know if any suggestion are available .

Thanks

Sandeep
