The Tabs on top bug issues have been around since 1.5
I thought I was the only one having that problem 
They must hate OD+ the most popular program they have. They treat it like EA treated SimCity with little respect the way I see it.
I've never had any issues with any of the sim city games, and I've played them all... (still SC2000 Dos version running under dos box)
and I think the program gets treated fine... it works great for me and what I need it for.... no issues here other than the tabs on top thing....
