I had this tool in 9.3 vb6 that work great. Now that i have update to 10 my tool is broken. I've tried figuring it out but i have not had any luck. Can some one please take a look? it errors at " If tmpPoint1 Is Nothing Then". Thanks.

Private Sub UIToolControl1_MouseDown(ByVal button As Long, ByVal shift As Long, ByVal x As Long, ByVal y As Long)

It seems to not recognize the first click temp.

Anyone have any suggestions, ideas or thoughts?
