# WinForms Plugins Causes Editor to Freeze or be Unresponsive
If you're creating or using WinForms plugins with the Editor and experience issues with freezing or the Editor being unresponsive.
A possible solution is to disable WinForms from installing its synchronization context:
WindowsFormsSynchronizationContext.AutoInstall = false
This value is
[ThreadStatic] and should be disabled in all threads.
