If you mean that the Asset List doesn't let you choose more than a few assets or show next pages that I think you'll have to open a SR.
I tried to choose assets in asset list and found nothing wrong.
In any case try to delete temp files maybe restart the sysaid service on the server, just a wild guess.
I have worked out that this is tied into another problem where the assets are not importing with all the information..
I'll marked this forum as closed for now..
Thanks for your help
