For some reason when I go into the drivetrain section and try to update the parts, it dosen't show the changes that I made when I refresh the page.
It seems to work in the other sections but not this one.
Tim - Which registry entry is this happening for you on? Also, which web browser and version are you using? I just tested it on my machine and it's working OK so it may be a browser-specific bug that we have overlooked.
Tested this out on our end and it's still working. We noticed that we have a confusing "Done" button in addition to the "save" button. Can you try again and click the "save" button? "Done" should really just be called "cancel" because it doesn't save anything.
