Switching Tabs Too Fast Crashes Desktop.

[ElementalCrisis]

To reproduce, click on Dashboard and then click on Collection in quick succession, sometimes clicking each tab multiple times before clicking the other, both tabs will be selected and your log will file with errors.

Seems to be related to Collection as can only trigger when using it as one of the tabs.

Added locking for tab navigation which will help, probably needs the same in other areas but wondering if this will fix it.

Fixes it for me.
