Scenario: legacy app with TSpeedButtons on a TPanel mimicking a ToolBar (can't use a toolbar because of flexibility considerations).

Delphi 7.0 (build 4.453), Win7 Professional 64 bits

If the buttons are set to Flat, if I move the mouse fast enough over the buttons, sometimes the hotimages are left behind after the mouse has left the button area.

Before any mouse movement:

After some fast mouse movements over the buttons:

I attached a project that shows the problem:

Thanks in advance,

This issue exists only in Delphi 7 and older.

Standard SpeedButtons can have same behaviour there, because MouseLeave message is not always send to the control.

I will think how this situation may be improved. Also, I can suggest to use newer version of the Delphi.

Thanks for the clarification.

Since it's a legacy application, it's kinda hard to migrate it to a newer Delphi, but changing the TSpeedButtons to TsSpeedButtons does seem to fix the issue.

Thanks!
