What are limitations of Virtual Objects in QTP

1. QuickTest does not support virtual objects for analog or low-level recording.
   
2. The Web page or application window must be the same size and in the same position when recording and running tests s as it was when you defined the virtual object.
3. You cannot insert any type of checkpoint on a virtual object.
4. The virtual object should not overlap other virtual objects in your application or Web page.
5. You can define virtual objects only for objects on which you can click or double-click and which record a Click or DblClick step. Otherwise, the virtual object is ignored.
