The MCQ Activity not loading problem: I suspect it is a performance issue with MCQ. The next release will include some performance enhancements to MCQ as it wasn't very efficient in its database access in monitoring and learning. We have no quick fix we can offer unless we give you some of the updated code, but that would make your upgrade to 2.1 more complicated.
Would you be able to export the sequence and send it to me. Then I can try running it locally and see if 2.1 will be any better. If you don't want to make it publicly available then email it to me directly?
How can you delete user/etc? You can't. For the user, if you create them and delete them straight away then they will delete. But as soon as they are linking to a learning design or a lesson you can only disable them. And when a user runs preview, this creates a hidden lesson.
At the moment we don't actually delete lessons - when you "delete" them they are still in the database. So you can't delete a user linked to a lesson for data integrity reasons.
For groups/subgroups the removed status is as close as you can get to deleted. We considered whether or not to do the same as lesson - when you mark it removed hide it completely on the user interface but not remove it from the database. We decided that as it only showed on the group administration screens and removing a group by accident could have a very large impact, we wouldn't remove them altogether on the group admin screens. But if a group is marked as removed, then it shouldn't appear in any of the normal user screens.
Deleting an new version of a swf? Do you mean when you upload them via the HTML editor? If so, then the path to delete them at the moment is very hard. The swf file is kept on disk in the repository (c:/lams/repository or /var/opt/lams/repository I think) with just a numeric id. So you have to go hunting through the database to work out the numeric id, convert that id to the appropriate directory name and the delete the file.
We have been asked to allow people to delete files like this - we didn't allow it originally as learning designs can share the files and we didn't want people accidentally deleting something that would affect another design. We will look into this for a future of LAMS.
