Description Csaba Halász 2012-05-07 16:59:15 UTC
When exiting monodevelop which has a solution open, I frequently get the following exception, mostly (only?) if monodevelop window loses focus while shutdown is in progress (which takes some seconds).

ERROR [2012-05-07 22:51:14Z]: An unhandled exception has occured. Terminating MonoDevelop? True
System.InvalidOperationException: Handle is not allocated

Is this still an issue?
Comment 2 Csaba Halász 2015-08-20 13:57:15 UTC
No, I haven't seen this in quite a while, and can't reproduce it now.
