I just got done fighting with Adobe Photoshop in front of a live audience of people (which is pretty frustrating). Photoshop crashed every time I tried to open a file, save a file, etc. Pretty frustrating... but I solved it. The culprit was Version Cue from Adobe. Every time File Navigation Services were invoked to Open, Browse, or Save... Photoshop crashed.
Here's the fix.
1. Choose Photoshop > Preferences.
2. Click the File Handling tab.
3. Uncheck the Enable Version Cue box.
4. Quit and re-launch Photoshop.
