I installed Version 2.6.0-rc4: wsjtx-2.6.0-rc4-win64.exe. (64-bit Windows 7 or later). and it crashes from time to time and gives me the following message (Sub-process error Failed to close orphaned jt9 process) will not start again unless I reboot my computer. I've uninstall the 2.6.0 and re installed the WSJT-X 2.5.4 and everything seems fine again. I know the 2.6.0 Bata so I thought someone should know about this bug so if this is not the right place to share this information maybe someone can point me in the right direction
