Why is the middle mouse button not working over some windows?
|This page has been updated for Quick Access Popup v10.|
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 hotkey (by default, middle mouse button) only works 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.
