MX Draw Command Macro in MX SS3

Having installed MX SS3 I now have to go back and work on a project that was initially developed in SS2 and all input file based.  The cross sections are generated by a command macro provided by the local road authority (who are still on SS2) and that has worked fine up until now.  When using it in SS3 some unusual things start happening, including:

What should be the first section on the second sheet is placed as the last section on the last sheet;

If I set dpf pages to single drawing as multiple sheet models trying to go to the start or end of the sheets (with the pages toolbar) leads to crashes and even just changing sheets can sometimes crash.  If dpf pages are set to separate drawings it is much more stable.

Anyone else had any issues with draw commands / macros in SS3?
