Loss of "Called by"-functionality

[Polly Parrot]

This one drives me up the walls... I frequently use the "Called by"-feature, available from the drop down occuring when right-clicking a function symbol in the Class View. Now, for no apparent reason, this has stopped working! I have tried deleting all of the files in the Debug-folder, deleting the ncb file, checking that the Build Browse Info box is checked in the project settings and then re-compiling. All to no avail. Selecting "Called by" for any function renders... nothing. Not even an error message! Any clues, people! Thanx in advance for any tips on this one! ------------------------------------------------------------ "Pooollyyy!! ...Polly Parrot! Wakey-wakey!"
