Folks,
This isn't an IDL question per se, I don't thing, but it
happens when I am using IDL.
Suppose I have a PNG file named "test.png" in a directory.
Suppose I created the file last week, which is reflected
in the time stamp of the file.
If I run the program that creates this program today,
the PNG file gets created OK, but the time stamp does
NOT get updated. Even if I "refresh" the File Explorer
window, it retains the date from last week. If I delete
the file first, then the file is created with the proper
time stamp.
This is Windows 7 with all updates running IDL 7.1.
Any ideas about this?
Thanks,
David

I am beginning to understand why I am confused.
I am using a single File Browser in Windows 7 with the
file view being set to "Details". If I browse to a
directory containing, say, *.pro files, then my browser
interface has a column labeled "Date Modified" and the dates
reflect when I last opened and made a change to the
file.
If I now browse to a directory containing, say,
only *.png files, then the browser interface no
longer has a column labeled "Date Modified", but
instead has a column labeled "Date". This date is
no longer the date the file was modified, but
is clearly the date when the file was originally
created.
I realize this is Windows. But this is weird
behavior even for Windows! :-(
Cheers,
David
