To resolve this issue, apply the following update. 

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

By default, this update is disabled after you apply it. To enable the update, set the DWORD value of the EnableDoubleClickDetect registry entry to 1. By default, the EnableDoubleClickDetect DWORD value does not exist, and you must create it in the following registry subkey: 
This update uses the values of the DblTapDist and DblTapTime settings. These values specify the time and space threshold settings that define consecutive taps or clicks as double-taps or double-clicks. The default value for the DblTapDist setting is 20 pixels, and the default value for the DblTapTime setting is 600 milliseconds. You can optimize these settings for platforms that require more accurate tap or click precision. To optimize these settings, change the DWORD value of the following two registry entries:

• HKEY_CURRENT_USER\ControlPanel\Pen\dblTapDist
• HKEY_CURRENT_USER\ControlPanel\Pen\dblTapTime

Note By default, these registry entries are not present, and you must create them.

Known issue

After you enable this update, consecutive taps or clicks still do not work as intended in an application if the following conditions are true:

• The application is running on the RDP server.
• You want to perform consecutive taps or clicks that are within the values of the DblTapDist andDblTapTime settings in the application.
• You do not want the consecutive taps or clicks to be considered as a double-click.

For example, you want to click two times (such as when you draw two dots in a Microsoft Paint application). The distance between these clicks is less than the value of the DblTapDist setting, and the time between the clicks is less than the value of the DblTapTime setting. In this case, when the EnableDoubleClickDetect value is set, the two clicks are considered as a double-click (or a drag motion in the Microsoft Paint application), instead of the two single clicks that you intended.
