I have an ASHX file which generates a PDF report and then forces download.
my IE7 is configured to open new windows as new tabs.
when i click on the button,i see the tab opening, but closes its self immediatelly (half a second).
when surfing to the ASHX file and passing the data in the querystring, no problem.
in other browsers, and when opening in new window (not new tab) there's no problem.
