OpenStudio 1.13.0 files won't stay open. Closes on Save-As, Set Weather File, etc.
I've got OpenStudio 1.13.0 installed and whenever I try to open and modify an .osm, the file closes with no warning. It happens when I try to Save-As, Set Weather File, Import DDY, Apply Measure Now, ect. I've tried reinstalling, I've tried saving the file locally and on the network. I uninstalled and deleted leftover registry information then reinstalled. Nothing is helping.
Has anyone had/heard of this issue or know of what might be causing it?
UPDATES:UPDATE 1:
@Eric - This happens with all .osm's, even trying to save or set weather files on new ones.
@David - I'm using Windows 7 Pro SP1. I've tried a new file and files saved on a network drive and my local drive where I have read/write permissions. I've also tried deleting the same-named folder that is created upon saving (I can save, but not Save-As). Still having the same issues in all cases.
UPDATE 2:
Ok, so I have figured out (don't ask me how) that if I drag and drop any file from Windows Explorer over the OpenStudio window, everything works. I've never seen or heard of this being a solution to anything and I have no idea why that would fix my problem. Everything I've done so far is repeatable for me.
