Hi, We have some problems with corrupted, missing, and strange files appearing while running our application. 1. If you try to open any file than HTML or TXT with IE, the file disappears! How is this possible? The file is permanently deleted from system! 2. After deleting all files in certain directory with our C# application suddenly some strange files appear in that dir. One would thought that there is filesystem/RAM problem, but it is the same with many devices we tried. Any suggestions? Simon
