Hi Mathias.
Yes, I realised "Wrong IID or invalid handle" was not good
Unfortunately the log gives no clue to what the "Wrong IID's" are, or to what the "invalid handle" refers to, so I don't know what to fix or even look for!
I am running Portable and I updated using the built-in Multiupdate. As I said, everything functions perfectly and the app loads my default config without issue (last few lines of log below).
2016-04-26 22:33:08.851 Creating ExplorerPanel UI, took 6 ms (0:0, 1:0, 2:0, 3:0, 4:0, 5:2, 6:0, 7:0, 8:1, 9:1, 10:0, 11:0, 12:0, 13:1, 14:1, 15:0)
2016-04-26 22:33:08.866 Application Ready!
2016-04-26 22:33:08.882 Checking if new version exists.
I load 9 explorer tabs at startup (6 on the left and 3 on the right) - these are the 9 locations I use 90%+ of the time.
I use a -F switch at startup to load "MC_Start.ini" which contains:
[PANEL_1]
Side=L
Active=1
Path=C:\Alan\
SortAsc=1
ViewMode=3
Locked=1
AllowSubPathChange=1
[PANEL_2]
Side=L

SortAsc=1
ViewMode=3
Locked=1
AllowSubPathChange=1
[PANEL_3]

[PANEL_9]

Could that be the problem?
TIA
