[GNC] Gnucash suddenly cannot open the data file from Onedrive

[Mike Brady]

Well, it seems to be fixed, but I don't really know why. The directory 
containing the Gnucash files was nested about 3 levels below "Documents" 
in Onedrive, and became (and still is, in that position) suddenly 
unusable by Gnucash as I originally described. However, if I move it up 
to the root level of Onedrive (or just one level down, such as directly 
under Documents or Desktop) everything works fine, just like it does 
when working from a local disk in a directory not linked to Onedrive. 
Strange. But at least I have it all working again and am able to proceed 
with year-end fiddles. Microsoft ... 🙁
