(Formats: PSP, G3, RAS, IFF/LBM, BioRAD, Mosaic, XBM, XPM, GEM-IMG, SGI, RLE, WBMP, TTF, FITS, PIC, HDR, MAG, WAD, WAL, DNG, EEF, NEF, ORF, RAF, MRW, DCR, SRF/ARW, PEF, X3F, CAM, SFW, YUV, PVR, SIF)" so the problem is opening this particular image format - personally, I've chosen which filetypes I want irfanview to open, and restricted it to the filetypes I use mostly, jpg, jpeg, TIF, BMP, etc as well as those video types I use the easy fix is to open Irfanview's settings dialogue box and deselect irfanfiew as the default viewer for this file type. Alternatively, the new plugin pack version 4.23 http://www.irfanview.net/plugins/irfanview_plugin_formats.exe "fixes possible crash in loading of very large XPM images"
