I noticed the update later on the curse client, but oddly enough it did not recognise the version number, and despite a manual download and install directly from wowinterface it was a slightly lower version number than curse listed and stated as being modified.
For consistency I let the curse client overwrite it, but just was an oddity.
SBF does work now, there is one problem though. You can't dispell buff by right clicking them. It produces some kind of error, so I went back to the original wow frames and moved them with moveanything.
Yes, that's because buff addons have to choose between using secure templates (which provide right-click functionality but very limited sorting) or not using them (providing all sorting options the author can imagine, but no right-clicking).
This is a result of the 4.0 changes to protected functions.
Bison did not work propperly for me. Some buffs were stuck showing even when expired and some did not show at all.
I am now using the updated version of SBF but be warned! do NOT try to change any colors in it! You will get stuck in the color picker and a error message every time you try to close it.
I'm sure this will get fixed in a future update
