Hello Support Team,

we have several projects with teechart and speedbuttons on the TChart surface.

Using Delphi XE2 (please try the attached sample) the Chart (left one) freezes after pressing the speedbutton
(speedbutton property transparent=False). Please try to zoom and nothing happens...freezes

The Chart (right one) did not freeze after pressing the speedbutton (speedbutton property transparent=True).
Zoom and unzoom works fine...and after many (ca. 100) zoom and unzoom actions the Chart also freezes.

Did you have any ideas how to fix this issue?

Hi Dive,

Thanks for reporting. I could reproduce the issue here and added it (TV52016411) to the defect list to be investigated.

Did you have any ideas how to fix this issue?

Not for now. As a workaround you could use a TButton instead of a TSpeedButton.
