iTunes 4.8 for Windows is suffering from compatibility issues with the popular Podcasting client, iPodder.
The iPodder team is looking into these problems, which do not affect Mac users.
"The recent iTunes 4.8 update breaks the COM connection between iPodder and iTunes", the team said. iPodder update 2.0.3 addresses these issues, but some users continue to suffer problems.
The team hopes to work more closely with Apple to prevent such issues being raised again in future.
