Take a default AdvGlowButton and put an image in it, the Image displays in the centre of the button, so far so good.
Now set the DropDownButton to "Enabled". The overall button width stays the same and the image moves to the left to allow for the DropDownButton.
However at run time the image moves to the right and so is no longer centered within the button.
So we end up with the distance between the left edge of the button and the image being larger than the right side of the image and the start of the DropDownButton.
I know this is a bit picky, but it would be nice to have this fixed. Once you have noticed it, it sticks out like a sore thumb.
Setting the AutoSize property has no effect and the Layout property does not improve it either.
We have applied an improvement for this. Next update will have this improvement.
