hi,
I am glad you asked, I have them fixed actually. I even tried having a fixed width xtaskbar image. The strange thing is after having them fixed, and the background stretched to full size. I did a !alert $taskbarcurrentwidth$. It showed me my fixed width....
Here is my config: xtaskbar 1.2.5.dll
*xTaskbar taskbar2
taskbar2X $button4X+button4Width+1$

taskbar2ButtonMaxWidth 150 ; ***delete this for xtaskbar 1.2.6 and up***
taskbar2ButtonMaxHeight 32 ; vertical distance between buttons, default 32
