I opened an existing file, did a save-as B4.txt
The new file showed up, and a new entry in vsdelta for this file.
BHB: B4.txt is the most recent entry.
Select it, then select the same in the lower pane (the lower pane has only this one file).
Click "View": It shows Version 0.
Select 2nd most recent file in the top pane.
Select B4.txt again in the lower pane.
BUG: Click "View": It shows "Version -1"
"View" is ambiguous: What version is it supposed to show?
The most recent version, or the oldest version?
For example, see BHB_History1 attachment - I've created B2, B3 and B4.
There are several versions of each, each with a version number near the top of the file.
I selected the oldest B2 in the top, and B3 on the bottom, then VIEW.
View is showing the 4th version of the file, but the title bar says "Version -1".
