ER - Diagram in Toad

Hello !

Hope Im right here. I couldn’t find a other forum of Toad.

So tried to become familiar with Toad.
until a problem accured .
I tried out the function "Add Objects by referential integrity from Database " by clicking right if one Table is in the ER Diagram and if the table have some constraints.

So this work on some computer in the departmend well and on some not, allways with the same Database and same userschema.
Some Computer get the hole related Tables presented, and some get nothing.

Im sure there is something with the properties. We searched for this but
couldn’t find anything. Have someone any Idea where we can fix this and how???

Thanks.
Werner
