I installed a recent nightly build (also openxcom_git_master_2014_08_12_1512) (beware that lots of mods are installed, as making skyranger have only 10 places)
While trying to reorganize Skyranger placement, right clicking on a down arrow to make soldier placed at end of list (screen shot 1), all arrows are pushed to top of screen (screen shot 2)
Making some test on a standard install (i.e. without any mod), issue is different but still there (screen shot 3 and 4) : screen is "emptied"
PS : for both installation, I use "old" dll (I think from 1.0 ?) as they are not provided with nightlies (anymore ?)
