Mouse does not work in open file dialog in RegiStax V6. A workaround to restore
mouse functionality is to press the tab key until the combobox with label "Look
in:", then press down key to expand the item list and move mouse over one item
to make the mouse work again.
It worked very well in wine version 1.8.7, then switched to wine v4 and v5 and
stop working. It looks like wine opens two instances of RegiStax as in the
title bar appears "RegiStax V6 <2>", it might be related to the mouse problem.
Previous versions of the program are not affected.
