IE 5.5 & 6.0 problems with history.back() function

[ptbernar]

Hey all, I'm having problems with IE 5.5 and 6.0 and the JavaScript function history.back().

I have a button on my webpage that makes a history.back() call, after opening up a pop-up window, however, this function no longer works.

Tested the problem and it doesn't exist when using IE 5.0 only on 5.5 and 6.0

any ideas????

Thanks.
