When DF shows Taskbar Thumbnail Previews on my Vista64, it shows them animated.
I don't know whether this is the default setting or whether I disabled it, but the thumbnail previews of the normal taskbar are not animated at all.
They show/hide instantly as soon as my cursor leaves the taskbar or when I move the cursor to another application on the taskbar.
Is there a possibility to make DF hide/show thumbnail previews without animation?

Additionally, the previews windows have the resizable flag. The cursor changes its shape to a resize icon if you move the mouse cursor quickly to the edge of a thumbnail window. Imho, the cursor shouldn't change it shape as I can't catch the thumpnail preview to resize it anyway.

And lastly, the thumbnail window borders are not the same width as the normal thumbnail window borders.
The border widths of DF are 8 pixels, while the one from Vista are 7 pixels.

Thanks you for reading.
