I did a Winsock recording for a Java based application (using Vugen 9.52).When navigating to tree view to perform required correlation/parametersization,the right panel indicates that no snapshots are captured.
Same Winsock recording was conducted for other application like Iexplorer and can see the snap shots with required texts.
Please note that LoadRunner 9.x is out of support. I would advise you to upgrade to a supported version: LR 11.x, LR 11.5x or LR 12. Starting from LR 11.5 there is a new licensing mechanism and the licenses will need to be reissued.
