Issue with some variables not being recognised

[JohnB]

Dim Ctr As WREG12.Lowbyte          causes error "Ctr item not found" - compiles if LowByte is removed
Proc OSReadMessage(MessageID As Word), WREG12.Dword       causes error "Result item not found"  Compiles if .Dword is removed

I have only noticed this since the last update.
