Reloading in a Multi-user environment

Is anyone experiencing crashes when using the 'Reload' function.

We have four or five operators working on a large assembly; modifying individual parts from a central sever. If they ever use the 'Reload' function to refresh the assembly. It can and does crash regularly.

SW2009 SP4.1

Vista 64

Thanks in advance,

Matthew.
