    Hi There,

    I’ve got a strange issue with C1DockingTabPages captions vanishing (see attachment). It seems to me as if it could be a side-effect of an underlying memory problem because the issue only occurs with my app running for a while. After having re-started my application, everything works fine hence

    sadly I’m not capable to reproduce this behaviour as it is totally random.

    I use VS2019, C#, .NET Framework 4.7.2 and C1Controls 4.5.20222.566.

    Any suggestions? Thanks in advance.

    Hi Stephan,

    We tried to reproduce the issue as per your description, but we could not see the issue on our end. We suggest that you once test your application with the latest version of C1 controls (4.5.20223.588) and see if you still face the same issue.

    If the issue persists, we request you to please provide a small sample project, which has a similar form layout as your main project, and let us know if there are any specific steps you follow to reproduce the issue.

    Also, please provide the specifications of your system (OS build info, RAM, CPU) on which you can reproduce the issue, so we can investigate accordingly and escalate it further if needed.

    Thanks, and Best Regards,
