I'm using ArcGis 10.1 on a Windows 10 64 bit computer. ArcGis constantly crashes when I select a file to open BUT I've found that if I paste in the full file location and name it will then open. So something is happening when I try to open the file by clicking on it. Doesn't matter what time of file as far as I can tell. A few qualifiers, I'm new to ArcGis and am not a developer. Any ideas/help as to what's going on and how to fix? I uninstalled and reinstalled and that did not take care of it.
