I have to agree with you on this.
I have been testing hips on and off for over a year now and still haven't been confident enough to roll it out. Each version or update seems to open a whole new can of worms. I've found now that I have to manually install HIPS 8 onto XP machines due to drivers not passing windows testing, which mcafee insists isn't the case. Once installed, the computers are unable to access the network, without a little fettling, which only works temporarily. Windows 7 is another kettle of fish altogether, seems to install ok, but then hogs the system memory with memory leaks.
It's like we're beta testers and need to log support cases to get issues resolved. I feel the product has great potential, but finding it seems to be the problem.
Mini rant over...
