Search and reveal command


I use DevonThink 1.9.3 (french). When I perform a search query and use the reveal command (command-r), sometimes the revealed content pop-ups in a new window. And when I click on the Home or “top group” button of this new window (don’t know the exact english button terms, because I use the french version), window is empty. I say sometimes, because it often works without problems (no window pops up), but sometimes it doesn’t work and I don’t know why (low memory or something else). But it is annoying. Thanks for your help.
