I am developing an application and have had an issue which appears to have been around for the last month or so. We have an online service which creates .PDF files dynamically based of a query to our Database. This then displays the .PDF in a web browser.
It appears that something has occurred around 45 days ago, which now prevents the file appearing in Internet Explorer only. We have not changed the method in which we create the files and are still using the same components.
• The file appears fine when using Mozilla
• When using IE it blocks the file as if it would block a popup. It makes the 'Pop-Up
Blocked' sound, and the window appears briefly and then closes.
We have run through adding the name to the Safe List, turning of Pop-Up Blockers completely, removing any Virus and Internet Protection programs however it still stops the file.
To make things worse, the issue is only slowly spreading. We have some machines which are using IE and the file does appear.
This makes me think it could be a recent Security release form M$ that those PC's that can access the file have not installed yet?
Any ideas or area's to look at would be appreciated. Even updates to Acrobat Reader perhaps?
