People who are using Pro version of TeeChart components have problem compiling uniGUI packages. As a workaround I removed TUniChart component from uniGUI package and moved it to uniGUIEx package. Please note that you won't be able to use TUniChart component unless you're using the standard version of TeeChart shipped with Delphi. Please see ChangeLog for details. New build version 0.80.2.796 is available for download.
