SourceTree 2.1.2.4 (Windows 10) failed to start on multi-monitor setup

[Adrian Paul]

SourceTree 2.1.2.4 kept failing to start and launching the crash reporter dialog on Windows 10 (Pro Build 1607) where I have two screens arranged vertically (i.e. secondary display is arranged above the primary display)

This seems to be the related log message from sourcetree.log...

Hello! This should be fixed in the newest version (2.1.2.5).

[Adrian Paul]

Thank you Mike - I have installed 2.1.2.5 from here: https://downloads.atlassian.com/software/sourcetree/windows/ga/SourceTreeSetup-2.1.2.5.exe

(via https://jira.atlassian.com/browse/SRCTREEWIN-7346?focusedCommentId=1541353&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-1541353)

Disconnecting the secondary display allowed SourceTree to launch successfully and resolve the issue.

The other reason for logging this issue is because the ReleaseNotes for 2.1.2.4 refer to a possibly related change:

• SRCTREE-1330 Bugsplat Crash fix when opening the SourceTree Window with negative dimensions.
