My environment: IrfanView 4.23, Plugins 4.22, Vista Ultimate 32b, logged in as standard user, Core2Duo E6600.
Problem: When I use the DEL key to delete exactly(!) one selected picture (mostly JPG) in Thumbnail View, then it is pretty likely (ca. 35%) that IR hangs up itself. It depends on which specific picture file it is.
Context: If then I shut down IrfanView and use the Windows-Explorer to delete the same file, it is also pretty (but less) likely that the Windows-Explorer hangs up itself, too. If then I use cmd.exe to delete the file, it is always possible. - Running IrfanView with CPU core association 0 or 1 does not change anything. - Deleting more than 1 picture at the same time is always possible, even if it includes a problematic picture. - The same bug occurs if I use either of IrfanView 3.85, 4.10, or 4.20. - The problematic picture files have the same file attributes as all my other picture files.
Installing a Windows Update for explorer.exe has led to a change: The likelihood of a crash is reduced from 35% to ca. 1.5%.
Background: A couple of months ago a Windows Update had replaced explorer.exe; afterwards the 35% likelihood occurred. Now another update of explorer.exe of December reduces the likelihood again. I cannot remember whether the current frequency of 1.5% is the same as the original frequency because at that time IrfanView had had a lot of other bugs in thumbnail view.
IrfanView is my only program for that the bug occurs at all. If I use explorer.exe and do not use IrfanView, then the bug does also NOT occur. Therefore, although explorer.exe had a bug, it is rather likely that also IrfanView still has a bug related to deleting exactly one picture in thumbnail view by the DEL key, IMO.
