I have noticed similar slow down with my own editor control – basic text selection seems very sluggish. I used a sampling profiler and there seems to be a lot of FillRect32 calls in sAlphaGraph. This has not been noticeable before.

I am using SkinManager.Options.OptimizingPriority = opSpeed.

Hello!

I think, it's slow because scrollbars are repainted after each item adding.

Try to use these methods:

Code:

sListBox1.SkinData.BeginUpdate;
…your code…
sListBox1.SkinData.EndUpdate;

If it's slow still, then give me a small demo, please.
