177 0x8000ffff (Catastrophic failure) occurs when Java swing Tab clicked

Hi,

I am not sure that I understood if it was TestComplete or the tested application that crashed, but I think that Report Generator tool (http://support.smartbear.com/viewarticle/56673/) might help to provide Support (http://support.smartbear.com/message/?prod=TestComplete) with the information that might help them to answer your question.
