2711	_IELoadWait() hung in case of unknown error	anonymous		"I have Embedded IE and sometimes it error-out by showing ""404"" page not found. In this case _IELoadWait($oIE,0,3333) always hung forever.

It seems it happen because of some logic problem in Func IEComErrorUnrecoverable($i_error) as it return $_IEStatus_Success not only when @error=0, but also in case of all unknown errors.

In my case @error=1 and as result _IELoadWait() didn't check for timer to time-out going in infinite loop.
