I have a problem with strings in my application.

I have created a string in the String Table which happens to have been allocated a resource number as follows :-

#define IDS_TDB_LAG 32780

I have set up the following string :-
"Dry-Bulb Time Lag"

I also have a toolbar, with a button which has been automatically assigned the same resource number as follows :-

#define ID_SUN 32780

I want to set up a tooltip on this "ID_SUN" button to say "Run SUNCAST"

I do this by editing the Toolbar Button Properties Prompt.

HOWEVER...
This new string replaces the old IDS_TDB_LAG string.

How can I get around this? What resource numbers can I safely edit?
