I have few forms through out the software that have the same behavior in terms of the issue. It happens on my machine (development environment) and all the other machines that software have been installed.
All the forms have to ribbon that is working and displaying all the features absolutey fine, once it opened. When the form is been minimized and opened again, top ribbon is gone. Only white blank square is displayed where the ribbon suppose to be.
I tried to click or drag on the white blank area, but nothing happens.
I am developing software with VB.NET 2012 using Infragistics 12.1 on Windows 8 machine.
Is this a bug in the ribbon? We are working with Infragistics for a long time now and we never had this issue. It started to happen recently. Any thoughts?
Also I have enabled all the expressions in VB and non of them is getting thrown when this issue occurs.
Hello,
This issue occurs on my PC(development environment) and all the other PC's that software is installed.
On my PC I have Microsof .NET Framework 4.5 Multi - Targeting Pack installed.
Software that has this issue is targeting .NET 4 Framework and all the clients machines would have been installed with a full version of .NET 4 Framework.

We have tried to reproduce this on several Win7 machines with various OS themes managing DPI settings and etc. and we still not able to reproduce this. Can you please let us know if this happen on a single machine or you are able to replicate this on several machines. Is there any exceptions that occurs in the output while testing this, can you please enable all exceptions in order to check if any occurs (open your solution in VS, go to Debug menu, select Exceptions and check all checkboxes) . What is the version of .NET that is installed on this machine (exact version ).
I am waiting for your feedback.
Please find attached image with required information. The first table in the image is my colleague's PC and the second table - my PC's driver info.
Hope it helps.
Kind Regards
Luis and Rasa,
What video card and driver are you using when you reproduce this and if you reproduce it on different machines do you get different behavior if the video card and/or driver are different?
