I have been trouble with using the Vaccinator and other items/modes that use the 3rd alt fire mode as of late it seems tio be that my middle mouse input is not being reconised and it will not change the protection on the vaccinator.
I have tried to change it ibn my settings but I cannot find the key bind there.
I have uninstalled and re installed TF2 but still no help.
I am at this time verifiying the cache and attempted to try again.
I was asking incase it was a problem people have had and there's an easy fix or something I need to take to support. Any help is good here, thanks.
