Q:  When I paste a glyph/BMP with white in it into a button, the white disappears.  The glyph/BMP appears just fine if I paste into into a button in Paradox. What gives?

A:  Delphi selects whatever color is in the lower left corner of your bitmap as the transparent color for the button as it rests on the button.  If the problem is that you _want_ the white to appear in the BitBtns in Delphi, then edit the bitmaps so that the lower left corner bit is a color that appears nowhere else in the bitmap.  (That yucky olive color works -- who uses that? <g>)
