Hi folks!
I think that this is a minor UI glitch but in the way of such things, it's a really irritating one.
I have Windows 8 (although this also occurred with a possible work-around in Windows 7; I can find no work-around in Windows 8) with DirectoryOpus 10.2.0.1 (downloaded it to see if I could fix it). I have a DOpus toolbar on the right-hand side of my screen which is arranged in "Taskbar" view. When I maximise windows, I would expect them to maximise up to the toolbar; however as you can see in the enclosed screenie, it maximises up to the edge of the screen; obscuring part of the window when the toolbar is "always on top".
In Windows 7, I could set the toolbar to hide, hide it, then unhide it and set it back to not hide; and windows would then maximise "correctly" until some unknown event caused it to stop working again. This doesn't work in Windows 8.
You'll also note the gap at the bottom end of the taskbar - this did not occur in Windows 7 at all; the taskbar would be the full height of the screen.
Thanks for listening.
