Oscar App - Unresponsive

[mark.apnea]

(sorry if this in the wrong forum)

Oscar app is unresponsive after loading last night's data.

1. Data seemingly loaded without issue
2. Clicking "View Daily" does nothing, no other options functional
3. Closed & restarted the app - same result
4. Rebooted Windows - same result
3. Uninstalled & re-installed Oscar - same result
4. Deleted all Oscar-related data/folders, uninstalled/reinstalled Oscar, reloaded data - same result

Anyone see similar issues with Oscar?

Not sure how to proceed from here. 

Suggestions or pointers?

Solution (hoping) -

I installed Oscar on a different computer without issue or complaint...so, probably not an application or update issue.  This lead me to suspect some level of corruption on the original laptop.  As I had fully uninstalled and deleted all Data and Config folders without improvement, I suspected a lingering registry issue was the cause.

I searched thru the registry w regedit and deleted all the keys/subkeys mentioning "Oscar".  A few keys/entries were blocked from deletion, and a few related to History, which I left alone.  Usually it is not advisable to delete registry entries, "Oscar" was a unique term which did not present any ambiguity identifying and deleting.  Its amazing how many registry keys are left behind even after an app and its data are fully and formally uninstalled.

A fresh app install, reloaded 13 months of data, and all is good again!  I am presented with the "Welcome" screen as normal (I did not see this before clearing out the registry).  Nice.
