Using RFT v8 to test RTC 2.0

I want to use RFT v8 to do some testing on both Web and Eclipse RTC 2.0 clients.
I am having some problems when using data driven commands to drag&drop the hand into the field. Fields are not being recognized.
See screenshots for more details.

Although some combo-box are recognized, I can't do the same with, for example, the Description or Summary text field.
In this case, the field seems to be recognized but again a data driven error appears, see screen 2 also:

I tried with Firefox 3.5.2 and IE7.
I am actually getting an error when enabling Firefox on RFT Test Environments.

IE7 is enabled, but the Test result Failure. I already followed the steps (regsvr32 RTXIEEnabled.dll blabla)

I am using java 1.6.0_13 and will try going back to 1.6.0_5


Is there any other configuration that must be done in order to make this work?

Thanks in advance.
