Ok, I read the posts for the last few weeks... Not sure if I am looking at this differently than others described their issues of I am seeing a different problem.
Basically I upgraded from 3 to 4 w/ the release of 3.02. W/ Bar3 I had bars one and two tied to 2 keys. If I hit "q", then bar 1 would show. If I hit "e", then bar 2 would show up. This "basically" still works, but now the icons will not change and/or show up as the one on the other panel. They are still what I assigned them, but they just show the icon for the other bar. It isn't always the same buttons that don't switch, but it can be different ones. Both bars have State based switching turned on and Action bar paging turned on. Cooldowns show correctly, Along w/ Macro Text and other stuff even if the icon is incorrect.
I can still use them as they are suppose to be, but I am kinda playing blind... Normally this wouldn't be an issue, but w/ the new skills and things, I have had to change up where some of my skills are.
Also, I have it swap to bar 7 for stealth on both bars. That works just fine. Stealth buttons never bleed through or get bled on.
Edit: Figures... I fixed it... Not sure if this is suppose to work... I enabled Action Bar Paging on Bar 7 (Stealth Bar). Now Bar 1 and Bar 2 behave how I want them to and show the correct icons.
