Will not open if CheckForUpdateWrapper::distribIsLatest() hangs #183

Closed edscott closed 4 years ago

edscott commented 4 years ago

Working from behind a proxy, with some apparent network trouble today, application will hang before opening any window. Seems that some timeout is required so that the check for the latest version of gams will not hang gams-studio.

This is the traceback from GDB:

Thanks for your detailed report. I can confirm that there is an issue if the network connection is interrupted. I inform you as soon as we have a fix.

Hi @edscott, the startup issue has been fixed and is part of the develop branch. The fix will also be part of Studio 0.12.7, which is planned for this week.
