Thank you very much.
My program was solved that problem.

I use TeeChartPro7.7 in BCB6
LoadChartFromFile function occur error message of[EClassNotFound 'Class TPointSeries not found']
I have included TeeEditPro.hpp.
=> #include "TeeEditPRO.hpp"

Thank you for your fast reply.
I Solve the problem with "TeeChart7.07SourceCode".

1. Uninstall "TeeChart7.07Builder6" with Custom option.
2. Install "TeeChart7.07SourceCode"
3. Run "Steema TeeChart7.07Sourcecode\Recompile"

Then the problem didn't appear.

I have the same problem.
I installed TeeChart7.07 and TQRChart flickers in design time and run-time.
I use BCB6.
