Did I just switched character again?

Anyone else's getting this?

While playing spy, instead of disguising as a enemy soldier you just change for soldier accidentally? I thought it was kinda entertaining the 4th time this week.

You mean you disguised as a soldier from your own team? There is a key that switches between red and blu... (but I'm not sure you mean this).
Anyway, my answer would be "no". I don't play the spy frequently. Only when needed, when everybody else refuses to do something useful (like taking out sg or backstabbing snipers).

Both Spy and Class selection menus look quite alike so I tend to press "," instead of "4" to disguise. Causing suicide with respawn wait.

I have severe difficulty reaching for "," with me left hand :)
