hijack is not installed. hijack is wiped out after a fresh install of the main software (2.00 b11), right?

Correct, Hijack is wiped out after a fresh install of 2.0b11.

However, there is a serious bug in 2.0b11 that is fixed by installing Hijack. This bug might fix the problem you are reporting (although I'm not sure because I'm not clear on the details of your problem). So if you're running 2.0b11, then you should install Hijack, too, in order to fix the bug.
