strange that myphoneexploerer can't detect my android phone

[gedebe]

I've been using WinXP all the while until now, I've just changed to Win7 and out of sudden myphone no longer can detec.
But my phone is able to be detected by Win7 as a external storge which is normal behaviour for both version of Win.
Tried to install myphone software again both on my phone and win7 also did not help

I believe the phone can still be used as an external storage device (think disk or flash drive) even without the ADB Driver but Win7 will not recognize the device as a cell phone. Check to see if you have yellow icon next to your phone, when connected to the pc, in the Win7 Device Manager. If so, you need a driver installed.
