RH2019 - resizing image maps

Hi everyone, I use Robohelp for many years now and recently updated to RH1019.12 . In our Microsoft HTML help output we use lots of graphics with image maps to let user select his topic of interest on a dialog for example. Quite often, when updating the graphics, the related image map areas need to be moved and/or resized due to changes on the graphics. Doing this using the mouse cursor is painfull and takes ages to get correct location and size, especially when trying the re-align the image map areas. In earlier versions (RH2017, or in RH2019 Classic) one could select the imgae map by cursor, then move or resize using the arrow keys in combination with the SHIFT button. This is not possible any more in new RH2019 HTML interface. Is thiS  a bug or by design ? Or maybe there's a smart workaround (other than directly editing html code).

any help appreciated
