I am using Objectbar and Window FX the shadows at Objectbar leftside at this pic http://img105.exs.cx/img105/4597/untitled5yr.jpg are space and rightside ain't, how I can fix it?

Make your own shadow.

The way it is made probably has three or four graphics, one for each side. And the taskbar only uses one, in this case the bottom one. The graphic for that shadow is probably made with a bit of an offset. Or likely this is a shadow that is supposed to look like a drop shadow, over to the right, hence the offset to the right with the space on the left.

It isn't a problem, it is just the way the shadow is made. So the only solution is to make your own or find one that isn't offset like that.

Oki thanks.

Could someone point me in the direction of how to make winFX shadows. I'm very interested in making smoothedge type shadows, like the ones for VSs like Longhorn alternative Dark, PMK25, and OSx Tiger.

thanks
