Export CSV in Powerplay Studio 8.4.1

[ampt]

Before I got a new computer and IE 11, the Export CSV function would give a foot-long random name to the exported file. Now the file  has the same name every time: ppweb.csv.

One of our biggest Cognos users in our finance department likes to export a view, change the view and then export the second view and compare the two exports in Excel without saving anything. Now she can't do that because they all have the same name and Excel becomes enraged when she tries to make the second export - with the same name.

Has anyone run into this?
