Visual Studio + Crystal Reports + SourceSafe = auto checkout

Question

I have a simple VS2008 project with several crystal reports, created with Crystal Reports 2008 (outside Visual Studio). The solution is added to source control (Visual SourceSafe 6.0). Now every time I open the solution all the reports are checked out together with their corresponding cs files. No changes are made to the files, so I can just undo the checkouts, but that's very annoying. Has someone encountered that problem and is there a solution?
Edit: Here is complete description what happens:

• Created several report with Crystal Reports 2008
• Created Visual Studio 2008 solution with just one project and added the existing reports
• Added the solution to SourceSafe and checked in everything
• Closed the solution
• Opened the solution (just it, not the reports) and the reports are checked out with no changes
  This behavior is not only for me, everyone working on the project has that problems.

Answer 1

After some googling I found that topic in the MSDN forums. My problem is identical with the one discussed there. The solution pointed is updating Crystal Reports. I'm gonna try that when I have time.
Edit: Yep, it's fixed! :) For anyone with the same problem - just download and install the latest service pack from the Business Objects downloads page.
