I am trying to to add the Transparent-Color property to Push Buttons in AcuCobol-GT, Version 10.  

In the below screenshot, I would like the grey around the buttons to be transparent, allowing the blue to show through. 

I’ve attached a couple of the bmp’s that are currently in use.  I’ve tried converting these to 16 color, 256 color and 24 bit bmp without success. 

I’ve also tried several different values for TRANSPARENT-COLOR in the push button display, using working storage values as well as the integer itself. 

78  WS-TRANSPARENT     VALUE x#c0c0c0.       |Windows Gray 192,192,192

<OR>

78  WS-TRANSPARENT     VALUE x#1000000.    |BM-CORNER-COLOR from ACUGUI.def, as mentioned in the Acucorp doc). 

I've tried the following in Display Push-Button:

TRANSPARENT-COLOR WS-TRANSPARENT

<OR>

TRANSPARENT-COLOR  16777216

From the program:

  DISPLAY PUSH-BUTTON  FLAT

         SELF-ACT

         TITLE SWPUSH-TITLE

         LINE SWPUSH-LINE POSITION SWPUSH-COL

         LINES SWPUSH-HEIGHT SIZE SWPUSH-WIDTH

         TERMINATION-VALUE SWPUSH-ESCAPE-CODE-X

        TRANSPARENT-COLOR  WS-TRANSPARENT

         BITMAP-NUMBER 1

         BITMAP-HANDLE SWBITMAP-BITMAP-NUMBER

         HANDLE SWPUSH-HANDLE.

 Is the syntax correct? Everything above, except for the Transparent-Color property, has been in place for some time and works.  This still functions the same as if the property had not been added.

Is the type of bmp compatible with what I am trying to do?

Can I see an example using this property that is working? 

This seems like it should be very straight forward  so I feel like it must be something simple that I am missing.  Any suggestions are greatly appreciated!
