Hi Marcel I went to truck and installed that package. The bug went away. Thank you. ---- On Wed, 06 Oct 2021 05:02:15 -0400 Marcel Taeumel <marcel.taeumel at hpi.de> wrote ---- Hi Timothy -- Still not sure how the VM could crash.

Yet, the resizing/positioning bug when dragging the left bottom handle is for the Morphic team. :-D I cannot reproduce the segfault on my Windows machine, just the jumpy dialog window. What VM are you using? Thanks for reporting!

Open Monticello. Open a remote repository (not sure if being remote matters..but for brevity sake) the repo window opens towards the right of the screen. Open a local repository. this opens more to the left of the original. on the remote repo on the right, highlight a version ad select "copy". the teeny window with the available repos opens. Select the left bottom handle and drag to expand it. segfault. Right bottom handle does not have the issue. cheers, -------------- next part -------------- An HTML attachment was scrubbed...
