Figured out what was the problem with IE8, BD, etc.
IE8 and Spybot - Search&Destroy issue
Solution: de-immunize all. Remove ticks next to all IE entries, then re-immunize again. It will ignore IE.
If you are using SpywareBlaster too, then after re-immunisztion in Spybot go to SpywareBlaster and enable all protection again.
Why did it affect BD? Simple (I think). It either depends on IE or the last book I edited in BD was in HTML format. Thus starting up BD was causing the same problem as starting up IE8.
Removing immunization in Spybot makes IE8 a vulnerability, but then when IE was not one?
