Exactly the same for me, three days searching what caused the crashes, today I uninstalled WB 7.9 and chrome works fine.
I've been running Chrome, first some v27 releases, and now v28.0.1500.20 Dev, both with Windowblinds 7.90 and now with Windowblinds 7.91 -- and have never had any problems with any of these combinations.
So, it's not just the Chrome Browser. There must be something else involved, as well.
