[Wine] expanding wine desktop

[rtrdom]

Wine is installed in Ubuntu Gutsy. It shows up on desktop when called from
terminal. However it is only about 3 inches wide on 17 inch display. Cannot
get it to expand. Have tried all display modes on this machine. Does not help.
I can see when clicking on a tab, something happens but cannot tell the name
of the tab nor what it displays after clicking on it. Does anyone know how to
correct (expand) so it can be read?
Thanks.
