I have seen cases where a programmer used public variables because he simply didn't have a thorough understanding of form properties. This causes possible problems, #1, obviously it can conflict with the same variable used somewhere else, and #2, the situation that the form may be opened more than once had not been considered.

If you can take the time, you should certainly try to convert the public variables to form properties - in such cases. But it is necessary to check for each and every variable whether it is not used in other forms - i.e., it may have been used to exchange data between forms.

In cases where data is exchanged between forms, there should usually be some better way, as well - but it may be more complicated to solve those cases.
