#3 hift-tab does not work

[Anonymous]

While in a game or watching a replay, shift tab toggles
between real and ally colors. While turned on, your
units and buildings are green as usual, but teammates
are yellow, enemy is red.
Wine dumps this message:
(20020804 with your "patch" copied over and compiled)

err⌨️X11DRV_ToUnicode Please report: no char
for keysym FE20 (ISO_Left_Tab) :
err⌨️X11DRV_ToUnicode
(virtKey=9,scanCode=F,keycode=17,state=1)

It happens only in DGA mode. Runnig wine under my
regular user account, shift-tab works well.
(This shift-tab is important in net games, especially 1v1)

Could you pls give some hints how to fix this?
