Tharrgor, what was the last revision you used "months ago" and what's the latest one you're using? It's pretty hard to give you a straight answer without knowing that.
Your profile says 4.0.2, so I'm assuming you were on 3.5 or some 3.5-xxxx build beforehand. You really ought to try the latest development revisions (4.0-1130 at the time of this writing). They've gotten a lot faster than 4.0.x stable builds.
