Short cut arrow

Hello
I have been using Tweakui for many years without any problems,I have 2 computers with the same exact software,This week I upgraded both computers to 1 gig, one being a celeon and the other being a pentiun III. I did a windows update and installed Explorer 6 after that the light arrow became black with white short cut image(default).The one with the pentiom III has the light arrow short cut the celeron has the black arrow.I checked the Q @ A and went into the registry, I have the registry key of 29 with the tweakui,2 for the light arrow.I went into safe mode and deleted the shelliconcache file to no avail.
I also went into display properties and looked into changing the icon size but couldn’t find a place to change this.
Any help will be appreciated
