skinned controls plug-in & display details button

I tried the suggested method to get the "Show/Hide Details" button to be "re-skinned", but it looks like it is not getting skinned in the first place at least in version 1.2. The other buttons on the bottom of the panel are showing up skinned just fine for the install progress panel. Am I missing something, or do I need to go back to version 1.1 to fix the issue?

!ifdef SKINNED_CONTROLS
SendMessage $HWNDPARENT ${WM_MENUDRAG} 0 0 ; Do this to force reskin
!endif

You can go back to version 1.1 (or you can fix the plug-in and upload it to wiki).

I am not sure but I suppose the old versions do not support Windows 8/8.1 x64 bit mode (and maybe newer Windows too)
