Windows Themes are supported for any applicable GUI controls, provided that the file ashw32.exe.manifest is present in the same directory from which ashw32.exe was launched. Themes provide various visual enhancements, such as buttons which automatically highlight when the cursor passes over them. However, a downside of Themes is that you lose the ability to control the colors of most GUI objects. The one exception is that you can still control the foreground color of text objects, but you must add 64 to the foreground color parameter (fgc) of AUI "CONTROL", MX_WINCTL, or AG_CONTROL commands.
