Hi,
the following HTML/JS/CSS-Code crashes IE6 immediately through a
combination of:
1. textarea in table in div
2. css:overflow-y:hidden
3. changing the scrollbar-base-color
4. moving the div

I think IE tries to move the native OS-scrollbar-widget, which is not in
place.

If point 3 is removed, the page works fine.

This looks like a benign crash to me. On my system IE is tanking in MSHTML.dll at 0x6360CD44 while dereferencing a null pointer (or a 0x22 pointer, to be precise).

6360CD38 mov dword ptr [esi+9Ch],eax
6360CD3E mov dword ptr [esi+90h],eax
>6360CD44 cmp byte ptr [edi+22h],0 ; edi = 0
6360CD48 jne 6360CDDE
6360CD4E cmp byte ptr [edi+23h],0

Stack:
> MSHTML.DLL!6360cd44()
MSHTML.DLL!636199e3()
MSHTML.DLL!6360b569()
MSHTML.DLL!6360ba22()
MSHTML.DLL!636ff83b()

Maybe I'm missing something, but it seems pretty run-of-the-mill.

Cheers,
