After a few seconds, moving objects right doesn't work

[SuperDisk]

Here's an example. Once about 30 objects are there, the moving right bit just stops working altogether. Why is this? How do I fix it?

It's all in the object selection. MMF2 doesn't handle object selection very well, so after there are too many objects, it breaks. I fixed it using a ForEach loop. NOTE: You will need the ForEach object for the example to work.
