Error with Xbrowse many fields

I faced that error when I increased number of fields in Xbrowse.
My version is FWH 7.01 :

Ehab,

Check if these values are the same:

MsgInfo( ::Fcount() )
MsgInfo( Len( oBrw:aCols ) )

Whats the source code for ::FCount() ?

MsgInfo( ::Fcount() ) : gets 84 which is the number of fields
MsgInfo( Len( oBrw:aCols ) ): gets 35 !!!

It is highly desirable to assign
Code: Select all  Expand view
oBrw:cAlias := <Required Alias>

soon after creating the browse object.
