As you might remember I use ZLog files a lot. This release is interesting as previously it started with the view you had when you saved the ZLog. Now I see two odd behaviors. I usually save the ZLog in the 3-pane view. On restarting if the directory under the cursor had been logged I get the 2-pane view. Also sometimes it starts in the 3-pane view with the divider between directory and file windows missing, which then reappears when you change to a new drive, I believe this is with ZLog files saved with v175, my previous version and not ones from 178.
HOWEVER 178 does seem (in initial testing) to have solved my crashing issue, which is great. I'd tracked it as far as whether four adjacent local sub-directories were logged or not, but haven't been able to refine it any further.
