We have made a number of changes to the RadEditor for MOSS since the official release of version 4.41. One of these changes is to the file browser content provider - it should automatically publish and approve files you upload if you have enabled the minor versions or content approval from the list versioning settings.
If this is a major issue for you, please open a formal support ticket and we will send you a hotfix build with the above change. Otherwise, you can wait for the next RadEditor for MOSS release (scheduled for the second half of December) and get the fix when it becomes official.
