We recently converted a VFP 6 to VFP 7 and found that the behavior of the display of the list items in a Combo Box was different between 6 & 7.

Assuming that the total width of the columns exceeded the remaining horizontal space on the form - VFP 6 would still display the line past the right hand side of the form. VFP7 only displays the rightmost column.
After we thought about this we realized that VFP 6 had a bug which was fixed in VFP 7.

My question is, based upon the above example, which other 'bugs' have been fixed in VFP 7 that might cause our application to work differently?

TIA.
