i guess moisture has done some damage .
i'll buy new Dongle (as i too need it

) [~Rs.200]. & report back in two days.
rit now after opening the Dongle case, i did some "filing"

& now the Dongle doesnt turn off (disappear) automatically, but the s/w is not able to detect the mobile phone, it just keeps searching (maybe the transmitter is kaput).
anyways i'll give you guys the feedback in two days.
& Thanks a lot for all the Help.
