Hi!
This behavior is strange, and I cannot seem to reproduce it with my tests.
For a better understanding of what the problem could be, could you provide me more details?
In particular:

• The 7-zip DLL you are using. Only 7z.dll supports the extraction of RAR4.x archives. Other DLLs like 7za.dll support only the 7z format.
• The architecture (x86 or x86_64) and version of the 7-zip DLL.
• The properties of the RAR4.x archive you're trying to extract (e.g., total size, number of volumes, solid compression, etc.). In this sense, a screenshot of the "Info" window (either of 7-zip FM or WinRAR) would be helpful!
