NVIDIA drivers: crash in unloaded nview.dll

[Jan Rysavy]

We have several reports with Salamander crash caused by NVIDIA nview.dll.
I saw this problem on my Windows XP with latest NVIDIA drivers during shutdown, while Salamander was running.
We are not loading nview.dll directly so it looks it's loaded by somehow (third-party shell extension?), later unloaded due to shutdown, while Salamander is still running.
The real problem is that this library probably register some hook that is not unregistered in library unload section. So our process is calling unloaded dll.

Any idea when and why is nview.dll loaded into process? We need to reproduce this problem to be able fill bug for NVIDIA: http://www.nvidia.com/object/driverqual ... rance.html

Pokial sa dobre pamatam, u nview.dll sa jedna o podporu viacerych monitorov. Overte si, ci klienti, ktori maju problemy s padmi pouzivaju viacero monitorov. Ja osobne mam Nvidiu GS7900 na jednom monitore a vyssie uvedeny problem nemam.

It doesn't look to be multi-monitor related. Some bug report samples:

Do you have nview.dll loaded in Salamander process? It isn't now on my computer...

PLease confirm that in "NVidia Control panel > Display > Set up multiple displays" is "Only use one display (single)"

Any idea when and why is nview.dll loaded into process? We need to reproduce this problem to be able fill bug for NVIDIA

What I would do is to examine all .dll's that were loaded or unloaded at the same time (doesn't the 'ms' info in the bug reports give you that information?) and search for registry entries for them. That could give you hint which shellExt is using it...

[SelfMan]

Further analysis:
The nview.dll is load while:
- right click on desktop
- choose properties > settings > Advanced > GeForce xyz
- push the button "start the nvidia control panel"

The control panel is now started and the DLL is loaded.
On my PC is the dll unloaded right after the panel is closed.

BUT when I start the control panel via tray icon, the nview.dll is not loaded.
