Here is a new version of "stCustomSliderIosOsx001" (not tested on Windows and android)
This custom slider works fine except this case:

(I don’t know if that is LiveCode or my brain who doesn't work as expected).
1. Click on the slider bar
The slider comes correctly
2. Do a mousedown immediatly and try to move the slider (doesn't work during 1500 milliseconds).
Suggestions are welcome
Best regards
