I have an issue in my Environment.
What is happening (and how the problem can be reproduced):
When another process is suspended (using Process Explorer) opening a document with "double click" on the document file, the Word takes too long to open.
When I "resume" the suspended process, then the document opens.
When a process is suspended, the Word or Excel Software can be opened without problem. And then the File can be opened with File>Open.
The problem is happening only when a document is opened with "double click".
This happens in Outlook 2007. As tested, I am not having Problems in Outlook 2013.
This is not a local Problem. The same happens on other Machines too.
I've reproduced this problem on both physical and virtual machines running the following operating systems: Windows XP Pro x64, Windows 7 Pro x64, Windows 8, Windows 8.1, Server 2008. Same problem with both Office 2010 and 2013.
Also, when a process is suspended (and it does not matter what process is suspended. It can be calc or notepad or any other process), if excel (for example) is already opened, double clicking the excel document will open (same as file>open). It seems like the problem is when the application (EXEL, WORD) is starting and not when its already opened.
