Altera Quartus II 4.1 double-click on QPF-File doesn't work

If I try to start my Quartus-Project by double-click on the QPF-File an 
error-window pops up.
I found the mistake: in the path to start quartus there are / instead of \ 
(I'm using Windows not Linux!).
If I change the Link, the double-click will work one time, thereafter 
Quartus seems to changes the Link again to the wrong one :-(

Can someone help?

Thanks, Manfred

Hi Manfred,

  Can you elaborate some more. When you say there is a Link, where is
the link and how did your create it? I have the following entries for
my environment variables

PATH %QUARTUS_ROOTDIR%\bin;
QUARTUS_ROOTDIR D:\quartus41

I have been double clicking on qpf's and launching Quartus II 4.1
without any problems. Also the Quartus II shortcut on my desktop
points to D:\quartus41\bin\quartus.exe.

You can send me email to pursue this further.

I've seen this same problem.  If I clock on the .qpf file it tries to
open the wrong application; trying to change which application is
bound to this extension shows a list of applications which doesn't
include Quartus; specifying the Quartus path directly via the browse
interface doesn't work either.

This is with WinXP SP2 (spit.)

Hi Peter, 

  Manfred did help us in identifying this problem. It had to do with
the usage of forward slashes in paths being used to register the
association of extensions. This problem has been fixed in the next
version of Quartus which will be released later this year.

Hope this helps,
