Hello,
I'm currently using Directory Opus 12.3.8 (Beta) on Windows 10 Pro x64 latest update. I am unable to resize the window of the dialog other than left to right. I notice there is an indicator (handle) on the bottom right corner of the dialog box, but it still only lets me resize from left to right. Stretching the window up or down does not work.
It can only resize vertically when the list of queued jobs is visible.
At other times, there is nothing* to use the extra vertical space so resizing is restricted to horizontal only.
(*I guess the speed graph could fill the extra space, if it is on, but the graph was designed with a fixed height in mind and making it bigger doesn't seem useful.)
The reason I brought this up is that I ran into a problem when I was comparing two documents on another screen by right-clicking on that screen's task bar and selecting "Show windows side by side" and for some reason caused another screen that displayed the Dopus copy/move dialog window to lengthen.
