CItrix 7.6 xenapp client screens freezing on applications

Hello,

We have an application that works fine, but then when the program opens up a message box, it freezes in Citrix and sometimes takes up to 3 minutes before I get the screen back.  

We tried the application locally and there are no issues, so we know it is a Citrix issue.  

In the citrix policy we have done the following: (see attachment).

Could anyone help us with the setting that would fix this?? We are using Windows Server 2012r2.

Here is the screenshot of the program with the message box sitting with a waiting status:

VBA.

What version of VBA - Visual Basic for Applications?

And, corresponding VBE.

If version 6, do you have Office 2010 installed on same server?

Actually I'd want to know if it is Citrix or the specifically the server before heading down this route.

Do you see the same issue if you RDP to the server?

What version of receiver are you using? Have you tried the very latest?

Do you see any spikes on the server when this is occurring? Anything logged?

I have found a few references to similar issues being solved by creating a policy and enabling legacy graphics mode.

There is a VDA core update available from July - http://support.citrix.com/article/CTX142642 - the one this replaces, also apparently resolved freezing issues.

Yea I would have to second that on the application issue.  Doesn't feel like Citrix related.  If you RDP to that same server and don't get the error you would need to have that same user RDP and see if they get the error.  

Sometimes, troubleshooting is process of elimination.  Otherwise, every application that is new that you put on 2008 R2 64 bit from Windows 7 32 Bit your run the risk of every finger pointing at Citrix with every new application added.  Best to dispel that myth early.

Best way I've found is to give internal developers a 2008 R2 64 bit development environment that they can use to create MSI packets or test APP-V and give them APPDNA with adequate training.

APPDNA analysis might just produce you a report that you can hand to the application owner that states in writing what is required to get that application working on those Citrix Servers.
