Thank you for your post.
Only FileMaker Pro 10 has been tested with Windows 7. Please see Knowledge Base Article #7453 for the latest information about Windows 7 and FileMaker Pro:
The system requirements for FileMaker Pro 8 do not include Windows Vista. However, many users appear to be using it successfully. FileMaker Pro 9 was the first version to be certified running under Windows Vista.
Thanks TSGal I appreciate your response.
