For what it's worth, I got the installer to finish without any changes to the Wine source, but I could not reproduce it.
The stamps.com installer spawns a second executable (also named stamps.com) which gets stuck calling WaitForMultipleObjectsEx in an infinite loop. The backtrace is attached.
Suggestions on where to go from here would be appreciated.
