Are graphics being cached?

[Paul A. Rubin]

Hi all,

I'm about to file a bug report, but I'd like to nail down the facts. 
Are graphic files being cached after conversion?  The symptoms I'm 
experiencing are as follows:

1.  Create a LyX doc and insert an image.  (Call this the old image.) 
The correct image appears in the GUI and View->DVI.

2.  Change the image file.  Close/reopen the document.  The new image 
appears in the GUI.  View->DVI still shows the old image (as does 
exporting the DVI).

3.  Close the document, close LyX, restart LyX, reopen document.  The 
GUI shows the new image, but View->DVI *still* shows the old image. 
View->PDF shows the new image ... after which View->DVI still shows the 
old image.

I haven't gotten around to rebooting the PC to see if I can get rid of 
the old image.  :-)

I'm not the only one experiencing this, but I'm on Win XP and the person 
who pointed it out to me is on Vista, so *possibly* it's 
Windows-specific.  Any thoughts?

Thanks,
Paul
