Summary:
I have just installed Citect 5.21 on my PC and can no longer see the variable property templates in Ortus.  

Solution:
The problem is caused by due to MDAC 2.1 which installs with Citect 5.21, Office 2000, SQL Server 7.0 and Visual Studio 6.0.

MDAC 2.1 Service Pack 2 does not fix the bug.

To work around this problem is to change the following queries in the ortus database using Access:

1) qryTemplSubVars : Change the return value for 'VarSegID', 'InternalAddress' and 'Address' from Null to -1.

2) qryTemplVars : Change the return value for 'VarSegID' from Null to -1.

3) qryEpuipSubVars: Change the return value for 'ContDataType' from Null to -1
