Accidentally I'd opened too many Slate's material previews and Max2018 got stuck. Since that I can't use Slate editor - it keeps trying to open bazillion of preview windows (even at the absolutely empty scene). Tried to reboot, deleted all the temp files, autobackups and MtlPool.tmp - no change, it keeps opening empty preview windows for hours on end. Any ideas how to stop it (except exterminatus)?
Also, is there any way to prevent opening multiple previews in Slate editor?
