Sure. Can you post a link?
One thing to check is the TaskbarHeight setting. For example, this is in the Uber skin:
The taskbar image height in Uber is 46 pixels, so in this example we want 46 pixels visible. The taskbar window itself is 48 pixels wide: the bottom 2 pixels are offscreen, but we don't want to waste the image on anything that isn't visible. However, assuming a standard 4-pixel border thickness, if we exclude the top and bottom borders from the taskbar, that gives 48-8=40 pixels. So in the Uber case, TaskbarHeight=40 means that we want the client portion of the taskbar to be 40 pixels wide. This probably sounds strange that the setting is for the client thickness instead of the overall window thickness, but the setting also determines how much the taskbar grows by when you drag the border to have multiple rows. In this case, it grows 40 pixels at a time, so the Uber taskbar thickness is always 40*rows+8, where the extra 8 pixels are from the top and bottom borders. Remember, though, that the bottom 2 pixels are always offscreen, so your image should not cover those pixels.
Let's try another example. If your taskbar image is, say, 31 pixels high, then it corresponds to a taskbar window that is really 33 pixels high (the bottom two pixels are offscreen). Take 8 off that to remove the top and bottom borders and you get 25. So in this case the setting should be TaskbarHeight=25 to cause the taskbar to grow 25 pixels at a time. Basically, the setting is the image height minus 6 pixels.
(forget all this...I'm having a brain-dead moment. The setting is the total visual thickness...so if you want to see 20 pixels, set it to 20).
Now that the skinning engine is getting pretty powerful, SmoothText is really hurting for some comprehensive documentation. Does anyone want to volunteer to write some?
I'd probably need a link to your theme to try to figure out what's wrong with the window borders.
As a status update, the next version will have improved support for alpha-blended window borders. I can't promise perfection, but in the last couple of days I've really improved its behavior.
