Unexpected close (repeated plenty of times)

[michalf]

I've installed 7.55a two or three days ago. Now, I am very disappointed with the stability. When I have tabs with remote directories (SMB), after couple of operations the application dies unexpectedly without any warning or error window. Most operation causing this are Ctrl+Insert on local disk, and Shift+Insert on remote disk, after tab has been changed (repeated two or tree times). But it dies on other operations too. The most annoying thing is that it does not report any error.

This happens on Win XP SP3 connected to other Win XP SP3 and SP2.

Are you using any plugins? Can you reproduce bug with clean INI?

To start TC with clean INI execute command line:

Code: Select all

"X:\path\to\TOTALCMD.exe" /i=clean.ini

[michalf]

Yes,
Suddenly disappeared after couple right clicks on some .exe file. With connection to SMB share on some tab.

I never before had similar problems while I am using Windows/Total Commander for over 5 years at work (corporate license).

Maybe some buggy shell extension?

Ctrl+Insert is like Ctrl+C - it's handled by OLE2 via context menu, which means that context menu shell extensions get loaded.

This is a very common problem, caused by a faulty/incompatible shell extension.

To correct it, please try the following:
1. Get the free tool ShellExView:
http://www.nirsoft.net/utils/shexview.html
2. Start it. On 64-bit systems, start ShellExView with /wow64
command line parameter.
3. Sort the shell extensions by type
4. Disable all context menu shell extensions one by one (you can hide/keep
those belonging to Windows, they are usually OK).
5. Continue until Total Commander stops crashing
6. Now you can re-enable the extensions which don't cause any problems

I will try if I have some spare time.

Why this not happened with 7.50a, if shell extension is the intruder?

[michalf]

I've found intruding shell extension, it was nVidia's one. When disabled TC worked fine. Now I have most recent nVidia package installed and following error appeared after couple hours of TC working in background.

That seems to be unrelated - it occurs when TC calls DestroyIdList to remove a local variable. Sorry, I have no idea why this should occur. Do you get this only in a specific directory? The icon thread is used to extract icons, overlays and thumbnails.

More info about offending context menu handler, which causes tcmd to close without any warning.

Additionally after I disabled this extension with SellExView, now Total Commander crashed with following exception on Ctrl+V on teb connected to SMB share:

EAccessViolation in TotalCmd.exe at 7C50FAA2.
Access Violation at 7C910CCE. Read of address 00000067.

With some error messages dialogs I cannot read shown in background. They are closed when I click OK on dialog with above exception. And I cannot move them. From what I can see it is about OLE incompatibility with Total Commander.

Found this recently, maybe it could help with the analysis?

Apparently you disabled the wrong extension then...
