I don't believe that is the problem as I have never turned on background entropy polling.
In the settings I have the following enabled
Erasing Report: After erasing unused disk space
Shell Selection: Add item to Explorer context menu
From time to time, when wiping multiple files eraser seems to hang on the last file. Canceling the erasing process causes eraser to stop responding and lock up windows explorer.
After a reboot everything is fine, but the file that eraser got stuck on is several Gigs in size, eg:
Wild cards are "*" and "?", I'm sure there are more.
if you used a wildcard of c:\temp\* this would erase everything in the temp folder.
If you used a wildcard of c:\temp\??a.txt this would erase every file in the temp dir that had at least two characters followed by "a.txt" eg aaa.txt...
Open up eraser, and go to the preferences\erasing.
Create a new erasing type and use a pattern with all zeroes. This will allow you to compress your disk image alot more than if you used any of the other wiping methods
