Ok, thanks. I checked out your trunk revision, and I think I see where this
comes from, this dialog does:

---
r->valueSlider.SetRange(-SliderResolution / 2, SliderResolution / 2);
r->valueSlider.SetTicFreq(SliderResolution / 8);
r->valueSlider.SetPageSize(SliderResolution / 8);
---

According to my testing SetTicFreq() makes a difference, because it updates
thumb position (TBM_SETTICFREQ does not have additional deferred update
argument, so it always updates). We currently don't touch thumb at all on
TBM_SETTICFREQ. Could you do a test build of your application without
SetTicFreq and SetPageSize call to confirm that it breaks on windows too?
