Small window

When Protel 99SE is minimized it brings up a very small window 7 x 23 pixels,
which must be minimized from the task bar, before protel can be maximised
again.
It seems to be a titlebar as it can be dragged when left-clicked.
How do i find the cause/fix for this, it is the main annoyance when using
Protel in wine.
Thanks
