Electronic – Altium – Cannot Select/highlight components on PCB

altiumcomponent-selectioncomponents

this issue arises out of no where periodically. Very frustrated!!

Suddenly I am unable to select any component on the PCB board in order to move it/right-click (the grey box doesn't appear).

I have tried selecting a box around the component but it does not highlight it.
I cannot even right click to see properties.
It is as if the component is gone

I can however, with 'cross select mode' in tools enabled, select the component in the schematic, come back into my pcb design and click 'reposition selected components', however once the component is placed i cannot then click back onto it to adjust or do anything.

After it happens i close it down, go back to an earlier save that i know was working fine, and the problem persists.

Can anybody think of any reason why it would do this??

maybe i have clicked a keyboard shortcut by accident?

You must make sure that the Components (or All Objects) object is selected inside the Properties panel in the PCB editor. You cannot use the mouse to click and select objects in the editor that are deselected in the selection filter. It's a feature you'll probably want to keep pinned to the sidebar.
