SUSE 11 sp3 cut-copy-paste works fine on VMware (esxi) 5.5 u2 but SUSE 12 doesn't.

It there a special flag somewhere or a package that may be required for this to work ? We had to set vmware settings to allow SUSE 11 to work but they don't seem to work with 12.

vmware host or vm settings
isolation.tools.copy.disable="FALSE"
