Weird issue with drop down menu

Hi
I have a strange problem with some (not all) of the arrow glyphs in AutoCAD. It seems to be cut off. I have tried various thing but glyph image is always distorted in some way.
The button is ReadOnly button, DropDownButton (not the DropDownButtonRight as usual) glyph AND DropDownButton image as the background for the glyph (can bee seen in the close up).
I replaced every image including glyphs for Pushbutton, DropdownButton, DropdownButtonRight, DropdownButtonLeft and copied all of the setting (content margins and sizing margins) from aero but the problem persists. Is there some other setting that may affect this glyph behavior? DropDownButton looks normal in other software afaik. I have tried some other VS and the problem is NOT present. Please Help

I don't have the app so its hard to say .Sometimes padding images with a transparent space can cause strange things to happen in different apps while they can appear fine in others.Also adding fonts can cause strange things to happen for some, not all people,but this is normaly at the pushbutton location.
If you say it's ok in some .msstyles its just going to be trial and error till you figure it out :(
I hope you get it sorted , Sorry I can't help you more

That is going to be a lot of fun :) Thanks anyway Dave .
and Thank You Dave, for all you are doing here .

Thank for the reply,
AFAIK it only happens in AutoCAD, but what are the chances that it could really be only that one application. I can post the files and margins settings but as I have said it happens even when I use default elements and valuse from aero.msstyles Is there some element that can affect the buttons ???

Well I'll keep looking for it, I must have messed something. Thanks :)
