Think I found it:

The code we have is:
if ( !(bRet = GetDiskFreeSpaceEx(sTemp.c_str(),&uiFree,&uiTotal,&uiUsed))
|| nFlag==2 )
test = GetLastError();

(nFlag = 2 is the DriveStatus func)

This means that GetLastError will be done if there is an error OR
DriveStatus was used. In the case of success (usual) the LAST windows
error will actually have been in the FileDelete code, GetGetDiskFree
obviously doesn't Set the last error on success. I think getting rid of
the "|| nFlag = 2" should do the trick.

When I write a line of code like that... I step back and look at it
and remark... piss, I dunno, looks complicated enough to work... :p

I fixed DriveGetDrive() over the weekend. If the current directory for a drive
is not root, it would fail on Win98. I fixed it by forcing it to look at root.
I will submit tommorow. I wonder if this is the same problem here.
