243	ListView control on Tab and WM_NOTIFY Event error + reproduction.	Shlomikalfa@…		"'''[Description]'''
>> I have a listview obj, created using the built-in inside a TAB at the 2nd TAB.
>> the items are inserted using a _UDF someone has donated in the forum...
>> it is being monitored by WM_Notify [just like in the help file].
>> when i click on entry #3, Row #4 of the listview, the TAB always switches to it's first TAB item.
