IrfanView 64-bit doesn't work in the Lister of TC 64-bit

[yong]

The latest IrfanView 4.40 includes a 64-bit version, which works fine as a independent application. But when I want to use it as a plugin for the Lister of TC 8.51a 64-bit, no image is displayed in the Lister.

Is this a fault of IrfanView, or Total Commander, I wonder?

You should ask the Irfanview author. The interface is very simple, TC starts the program, then uses WM_COPYDATA to send a conversion request and to get the thumbnail back.
