Firefox TruClient script with Profiling has stacked on Login to web application

Hi,

I didn't find similar discussion on that forum.

I created Firefox TruClient script which works perfect in all 3 possible variations:

(VUgen, VUgen with Firefox and Controller)

But, when I check the Enable Profiling checkbox script stacked on Login transactions.

AUT is web application used GWT protocol.

Anybody has an idea why it happened?

Thank you

Yuri
