I'm running:
AlphaControls 7.70
Delphi 2010
Windows Vista
Here is how to replicate the problem:
1. Create a new VCL Forms application in Delphi.
2. Add a SkinManager and SkinProvider.
3. In the SkinManager, set the SkinDirectory property to a folder containing skins.
4. In the SkinManager, set SkinName to “Black Box”.
5. Add a sSpinEdit control to the form.
6. Run the application.
7. Hover your mouse cursor back-and-forth horizontally over the right side of the sSpinEdit control so that the mouse cursor travels repeatedly between the control's edit box and its up/down arrows.
When I do this on my system, the glow effect “builds up” until a very bright orange color surrounds the sSpinEdit control.
The glow effect resets to normal if I move or resize the form.
This problem is not just related to the “Black Box” skin, it happens with other skins, but because they are lighter in color the problem isn't as noticeable.
I have found this problem also occurs with the sDecimalSpinEdit and sTimePicker. There may be other controls as well.
Thanks!
