I tried to create a user control that included a TxText control and a toolstring (within a toolstrip container). It works great (I used the SF richtextbox/richtextboxtoolstrip as a starting place) except when I use it on a form that I load via another thread (I instantiate the form on another thread, save it away in a static field). The form is a wizard form (SF wizard) and one of the pages has this TxTextControl user control on it. When that page is navigated to, I get a threading error saying that I can't access the toolstrip from another thread that it was created on. None of the other controls are having problems, just the .NET toolstrip. Does anyone know what the problem is?
