Thanks for the update! Sadly, most of your problems seem to be win32 related. Windows ought to be able to handle image transparency better but evidently this set of components may not have used windows hooks but tried to write their own?

In the upgrading of the D2007 program, one TImageList set of images (135) got mangled. CnPack has a very neat GUI for the image list that allows one to directly search the internet for public domain icons that one can then directly add to the imagelist. The only way to show transparency for this particular imagelist was to use the "Use XP Style..." checkbox, but like I said that only works in design time. At run time, the black background shows up. I did manage to export the 135 images which in the process converted the background from black to white which, although still not transparent, is much easier on the eye than black. For any readers, use of the XP Style causes other image lists to have a black background, but for these other lists, they were transparent (at run time) without the XP Style.
