Issues with Project Management

Good morning!  

I've noticed that when I have a change order that has numerous change requests pulled into it,  my system can't handle it.  I have to add a few slips at a time then save and continue unitl I've pulled all slips in, IF i can even get that far.  Most of the time my system will lock up and then eventually kick me out of PJ.  When this happens, what has been pulled into the change order is correct in PJ, however everything does NOT follow over to Contracts.  Has anyone else had this problem?

Thanks in advance for you help!!
