I just upgraded to 3.34, and the new infobar was noticed right away, for it had the `Windows Standard` color, instead of the color I specified for windows'.
As you can see on the folowing screenshots, it's only a small variation from the color used but.. it still stands out. Especially on the third screen where I selected a totally different Windows' scheme :)
Running on W2K Pro SP3
Interesting bug.. Though at least you can see the extents of the bar if you drop it in the wrong place or resize the window (which in some cases fails to resize the bar to fit). I wouldn't mind seeing the client take the current system settings, and depending on if it is a bright or dark color, intentionally make the bar a color that is nearly the same, 'except' being a little lighter or darker than the existing settings. Standing out is not imho necessarilly a problem, but not coming even close to matching the theme colors is.
Personally I think that the code to handle this kind of bar is rediculously buggy and would benefit from being completely replaced with a custom window that performs the same function, but does it correctly. The existing MFC code has some odd quirks.
Part of the problem, I think, is that it's not using Windows colors at all. The Infobar's colors are all settable; it's not just like another status bar or something. So if you want that background to be white, it can be white. It's not so much 'Windows standard gray' as just 'gray'. So the easy fix, I suppose, would be to set up some kind of script to change the colors when you startup. It's not particularly meant to 'blend in', at least I don't think so... it's just 'this color until you decide otherwise'.
If it's the wrong color and you don't use it, you can always switch it off entirely. If you do use it, just figure out what color you want it to be and set that in a script.
I could be wrong, but this is how I see it, anyway.
It is implemented as a toolbar from the MFC libraries. If it inherits the wrong colours, that is part of the library I use. As Neva says, you can control the colours yourself anyway.
