VFB is always on top of other windows even when Max is minimized

Does anybody know why my VFB is always on top of other windows even when I minimize Max? It even stays on top of other windows in Max and the quad menus which is a bit annoying. This started happening just recently which makes me wonder if it is caused by Update 1 of Vray as I’ve never had this problem before. Anyone else or is it just me?

Please check below the video I recorded.

EDIT: It seems that this went away after restarting my PC. Strange.

Glad that it went away, because there is nothing specific in V-Ray that would cause it. I’ve had Max windows stuck on top sometimes too - f.e. the Render Setup window or the Material Editor.

Best regards,
