I've had a few reports of people having problems viewing content in the just released 3.7 - as it happens, the WithStyle guys found a flaw in the html component - and they have a fix. I should have an update out within 2 days (I have to await their build). Once it's out, I'll redo all the builds and upload fresh, so that first time users won't have to grab the update. I'll post on this again when the fix is available.
Update: The patch is available. Grab Both WS updates and restart - things should improve after that
Update: Another tip - if you still see problems, check to see whether your system has hyper-threading support. If so, right click on the BottomFeeder process and set affinity to one CPU - that should address the problem.
