SYMPTOMS
Consider the following scenario: A Remote Assistance connection is established between an expert's Microsoft Windows XP-based computer and a novice's computer. The expert then clicks Take Control in an attempt to take control of the novice's computer. However, when the novice tries to grant control by clicking Yes, nothing happens.
