I have a vnc session with gnome2 desktop.
The following are couple of examples where multiple key press working as expected and the last two examples have unexpected results (with F1 & F2).
Please help.

In all the above examples:
- Shift key is pressed
- Other key is pressed and is released
- Shift key is released.

So, Holding Shift and Pressing F1 key gives the following result:
- Shift is pressed and (and Shift Key is released)
- F1 Key is pressed (and Shift Key is pressed)
- F1 key is released and Shift Key is released
It means, the shift key is being released when F key are pressed.
How to prevent this?
Alt is working fine with F keys.
The following is the xmodmap for that server:
xmodmap: up to 4 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_R (0x71), Meta_L (0x9c)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_L (0x73), Super_R (0x74), Super_L (0x7f), Hyper_L (0x80)
mod5 Mode_switch (0x8), ISO_Level3_Shift (0x7c)
The following is the xmodmap of another server where Shift + F keys works:
xmodmap: up to 2 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_R (0x71)
mod2 Num_Lock (0x4d)
mod3
mod4
mod5
I have tried removing the last 3 modifiers. But still doesn't work. Will it need to restart any service to take effect. If so, haven't done it. However restart of VNC completely resetting to its defaults.
I'v also tried to disable F keys. But don't know how. And even if I disable these F key bindings, Alt+F key commands won't work right. So I should not disable F key binding s completely.
Please help.
