4.0 Issues
Can't click off buffs
Correct. As of WoW 4.0, cancelling buffs is a protected action, meaning that the default buff frame can do it, but addons have to use a more complex and not-yet-completely workable means to do that. I thought I had a workaround, but it was causing huge problems. Hopefully Blizzard gets us a better way to cancel buffs sooner than later, or I can fix a workaround that's decent. Take it up with Blizzard: http://forums.worldofwarcraft.com/thread.html?topicId=27189091160&sid=1. As of SBF 3.1.25, there is an option to keep showing the default buff frame. It's a pretty piss-poor option, but until this mess gets sorted out it will have to do.
Tracking buff does not show menu when clicked
Cannot reproduce (do you have the frame set to clickthrough?)
Cannot negate "my" filter
Fixed in next update
Other Issues
Bar textures are stretched instead of being revealed/hidden
This appears to be a bug in Blizzard's texture handling.
ha filters do not work correctly
This appears to be a bug in the game client. It's reporting things like Recently Bandaged as dispellable when queried. Working on a solution for the long term
/sbf options occasionally freezes the game
Haven't been able to reproduce, looking into it
Timers for temporary weapon enchants do not update immediately when applied (scheduled fix: 4.0)
Timers for temporary weapon enchants flash randomly (scheduled fix: 4.0)
Saved variables sometimes reset for no reason
Working hard to track this one down. I know how much it sucks to have to re-set up things! I really hope to track this down for 4.0.
