Thanks Skipy. I will try again.

I use a GoFlight MCPPRO and have managed to program all buttons and switches on the aircraft MCP via GIT (Goflight Interface Tool from Pollypot software) but this software does not recognise the 7 rocker switches on the Bravo so cannot program  them, hence the FSUIPC mouse macro. The two remaining problems (well not much) for the MCPPro are IAS displaying -1 in VNAV and -8100 when not in VS. All other modes are fine.
