When i scroll to the next file containing a question mark i get this error:
Could not open file C:\test?.jpg: The filename, directory name, or volume label syntax is incorrect.
If i select test?.jpg and press F3 Pictview can open it without a problem.
AFAIK question mark is not valid character for filename in Windows, how did you create it? (Or it is at least not recommended, because ?, * are used as wildcards - I am not sure how would FindNext and other WinApi functions act on this filename when using mask '?')
