Windows 7.1 ULT 64bit
.Net Framework 4.5.1
PlayStationMobile (with MonoDevelop 2.8.8.4)
Norton 360
When attempting to open a script for editing the MonoDevelop 4.0.1 splash pops up twice but nothing more.
Task manager shows there are no monodevs running in the background.
I have read a number of other similar posts but have not identified a solution.
