On the Windows 95, 98, and ME platforms Thinstall must create a stub file in the system TEMP directory for each DLL it loads. This stub file is deleted when the program quits. The stub file will not contain any parts of the DLL code or data, but in some versions of Thinstall it may contain parts of the DLL resources (icons, dialog templates, etc). The stub file will have a random filename.
On the Windows NT,2k, and XP platforms no stub file is created.
