bug in TeeChart 7.02 for Delphi 2005 ?

Dear Steema-Team !
I encountered an annoying bug in TeeChart 7.02 for Delphi 2005 (Win XP). I use a TChart with a line-series to draw the history of a pressure in mBar. So i have to update the Chart every second. With the old version (TeeChart 7.00 for Delphi 7) everything worked fine, but now i get an "out of resources" - exception when the program runs for a few hours.
After a few tests i figured out that everytime the TChart draws itself new (after i add a new value) it uses 2 or 3 more, new GDI objects (you can see that in the task manager - just select more columns then the standard columns).
You can test that out with a new project and an empty form. Just put a TChart in it, add a new line-series and TTimer and add every second a new value (with addxy). With the task manager you can see the loss of resources.
Please fix that bug, because i can't use the component until then.
with kind regards,
The Punisher
