We installed new version our application with Infra 11.2 and it wasn’t helped. We don’t use multithreading.
What can we do to fix this issue? Reinstall frameworks? Put Infra dlls in GAC? etc. It is so critical for our client and us. Please advise.
As much as I want to, I cannot tell many from this information. Could you please tell me what is your scenario, what steps do I need to follow in order to reproduce that issue?
It would be even better if you could provide a small sample project which reproduces the issue.
We have a lof of clients but this issue reproduces only on one.If client restarts his PC this issue doesn't reproduce some time.But it happens again after 0.5-4 hours and client must restart his PC.All of our forms with Riboon core. Exceptions are the same.We reinstalled FrameWorks on client's PC. We don't know result.I remember that other our client had the same problem about year ago.We reinstalled FrameWorks on his PC. It wasn't helped. Client reinstalled OS b/c he couldn't use our CRM system.It's very bad situation for us.
Of course I can't create sample project.
Do you have any ideas how can we help to our client?We don't want to reinstall OS...Thanks.
I can understand that this is critical for you. It might be an already fixed issue, so you can try and test your project against the trial version of NetAdvantage for Windows Forms 13.1
Without looking at a sample there is not much I can do. I can only guess the cause, it could be the Operating System's theme(try something other than Aero), you could also try setting the 'IsGlassSupported' to 'False' on the 'ToolbarsManager' component.
We removed all FrameWorks (1.1, 2.0, 3.5, 4.0) and installed they.Seems it was helped.Client has Windows XP - so he hasn't Aero theme.Thank you.
This issue was appeared on client's PC after some weeks/moths.Client had to reinstall windows :(((((((((
Thanks.
Hi there,
I have been experiencing the same problem described above.
We have 40 machines running our application and only one of them is having this issue. When the user hover over the toolbar, the red cross shows up like illustrated above. I reinstalled the framework as suggested but the problem came back again after a while. To make things worse, the machine in question is the CEO's machine. Don't know what else to do. There is something in his machine which is causing a conflict with the Infragistics 2013.1 component.
Could you please help?
Thanks
I am glad to hear this. If you ever experience any kind of issue again, please do not hesitate to contact me again, I will be happy to assist you.
