Even compiling Harbour, hbw32, and my sources, with default flags I am able to host Active-X's and receive events properly (will be updating FreeWin shortly). No problems, may be for the time-being. But as you have pointed out above, it will be heartening to see it fixed sooner than later to avoid possible future GPF's or while manipulating comples COM objects. Can you guide me in this direction what exactly have to be done. I read in-between lines to understand (TO FIX) but what I could not figure out. I am just a beginner on C levels.
