Just trying to see if anyone else is experiencing the same issue as I, with 4.3.1.
Basically, a project is open; Any Project.
Then:
File → Open Project; Any Project.
…Freeze.
Only way to close Unity thereafter is to End Process in Windows Task Manager. Will Bug Report even help in this case? It happens on all projects since 4.3.1 was installed, so submitting a project doesn’t really sound productive.
If I open Unity, afterwards, the first project is still loaded but Open Project works just fine.
