nokia 5800 touch screen blocked when phone rings plz help me

[sihina22]

When my phone (Nokia 5800 xpressmusic) rings I cannot use the touch screen to answer. Can only use the coloured buttons at the bottom or the security lock side button.

Ya there's such a problem with the software but it's easy to use hardware buttons...
