wrong key logged when use Teamviewer

[bit4woo]

when I use teamviewer to connect to my remote computer ,and I run windows keylogger on both side.

remote side logged wrong keys:

when I use shift to input
QAZWSX@20153333
remote logged:
azwsx220153333
local logged:
[SHIFT][SHIFT][SHIFT][SHIFT][SHIFT][SHIFT]qazwsx220153333

when I use capslock to input
QAZWX@2015_6XXX
remote logged:
[SHIFT][SHIFT]q[SHIFT][SHIFT]a[SHIFT][SHIFT]z[SHIFT][SHIFT]w[SHIFT][SHIFT]x[SHIFT]22015[SHIFT]-6[SHIFT][SHIFT]x[SHIFT][SHIFT]x[SHIFT][SHIFT]x
local logged:
[CAPSLOCK]QAZWX[SHIFT]22015[SHIFT]-6XXX

the main problem is: we can't identify the char is upper case or low case.

a real case I encountered:

abc2015[shift]-6QWER logged, but the true keys are abc2015_6qwer

Is your keyboard QWERTY? If it's AZERTY it may not work.

I use QWERTY keyboard, both on local and remote.

Strange, when I run it remotely it's working fine. Does local work correctly?

local works fine. the strange situation only found when using teamviewer.
