I bought Aida64 today and seem to have found an issue with SensorPanel when setting it up today.
When the following option is selected: Preferences > Hardware Monitoring > SensorPanel > <Keep SensorPanel the topmost window (always on top)>
Using right click on the Windows desktop does not work, the menu disappears very quickly. The issue appears to be related to the refresh/update/polling for data. The right click menu appears, but as soon as the SensorPanel polls for new data and updates, the menu disappears. Disabling the option above rectifies the issue.
Holding right click for more than 1000ms (default poll time) means the desktop right click menu works fine.
