Why are QAP context menus not working in some windows?

In some setup, the QAP context menus may work in Windows Explorer windows but not in a custom file manager (like Total Commander).  Or the opposite.

This is generally because some applicatinos are running with different access privileges.

For example, if your file manager is running with administrator permissions while QAPmessenger.exe (that app transmitting commands from context menus to QAP) is running with standard permissions, messages sent from the context menu could not be received by QAPmessenger. Maybe you should run your file manager with regular permission or, on the opposite, launch QAPmessenger.exe with elevated privileges.

The opposite could also be true: if QAP runs in admin mode and Windows Explorer (or Total Commander) in standard mode, context menus in Explorer could not launch QAP commands because QAP has higher permissions than Explorer. Context menu can only call apps having privileges equal or lower than Windows Explorer has.

Why is the middle mouse button not working over some windows?

Note to power users with more technical knowledge about ACL: do not hesitate to use the comment form below to give more detailed or accurate information.

Most of the time, this issue is related to ACL (Windows Access Control List).

Each window in Windows is launched with a given set of rights. Basically, there are two levels:

  • user level (standard permissions)
  • administrator level (elevated permissions)

With elevated privileges, user can make changes to the system that can affect all other users on the system.

Quick Access Popup hotkeys (by default, middle mouse button) only work on windows that have equal or lower access level. If you start an application with an higher "administrator" privileges (using the Run As Administrator Windows Explorer menu), QAP will not have the permission to open its menu over the windows created by this app. To do so, you would have to also launch QAP with administrator privileges.

Is it a good idea to launch QAP as Administrator? You have to know that every program started from QAP will the also inherit these enhanced rights. This could allow them to do changes on your system without prompting you. From a system security point of view, this may put your system at risk. In other words, you have to know what you are doing.

Can QAP launch an application with administrator privileges?

Yes. If QAP is running with administrator permission, all applications it will launch will automatically inherit the admin level. But you should not run QAP with admin privileges unless you have good reasons to do so.

If QAP is running with standard permission, you can start a given application in admin mode only if required. Check the option Elevate application with administration privileges in the Advanced Settings of the Edit Favorite dialog box. When start it, QAP will ask Windows to launch the app with admin privileges. Of course, before launching it, Windows will display the usual approval dialog box or ask for the admin password.
