1. Bugs corrected:
a) WinRAR shell did not allow to create recovery volumes for locked RAR volumes. Now the recovery volumes option is accessible for both locked and not locked RAR volumes;
b) WinRAR displayed incorrect sizes for files inside of UDF ISO archives if file size exceeded 4 GB. Such files were unpacked correctly, but their sizes in file list window were displayed wrong.
