That is a very strange problem Bob... are you sure it is 7.75KB and not <8KB? 8KB sounds like a hard-disk sector issue. Is the filesystem NTFS (with 8KB clusters?) If it's NTFS, open your disk properties and perform a scandisk with fix on the disk(s) and reboot - could be a corrupted folder index or something bizarre like that. Good luck.
I am sure it is 7.75KB and not <8KB. I have the FAT 32, not NTFS. I doubt it is a hard-disk sector issue but I will run scan disk anyways....
What other possibilitys? Would reinstalling WAMP work? How do I delete every file WAMP has on my computer? Maybe I missed a file or two last time I uninstalled it?
