I update on the About dialog as well.
It does not show up multiple times in the Add/Remove Programs applet. I double checked using Revo, and it only finds one as well.
There is only one entry on the All Programs list as well.
Update: I just uninstalled Comicster and installed it again off of the website. This cleared up all of the redundant folders and files, and the start menu deal has been rectified.
When you publish the next update I'll see if this happens again.
