I constantly got stuck on the darn EFB while it is completely out of sight... It is due to you guys putting the 'tab' key as a shortcut for quick select input bars...
And whether it freezes the cursor or not actually depends on whether the cockpit cam is on 'fixed' cam or 'freelook' cam when it happened (usually switched by clicking the middle mouse), and if on 'freelook' then the solution of your earlier reply indeed works; but if it is on 'fixed' when it happened, then it is game over.
There is no need for a shortcut for input bars in my opinion, and if you guy deems it is necessary, at least don't make it tab key, as it is also used for default MSFS 24 EFB, and also for 'alt+tab' switching to other windows pages...
