Same thing occurs to me and my customers, driving me crazy!!
Here is my case: VB6 project with MDI, two screens frmDataEntry and frmReports. in frmDataEntry I have a user control having the smartUI.ocx.
frmReports is having a WebControl to display the content of the web site (Reports are web-based) In some reports, we use Silverlight 4.0.
To get it to crash every time: I open the frmDataEntry and display some data. Then I go to frmReports, and display a report with some Silverlight 4 code. Then in the Windows Menu, I go back to the frmDataEntry. Then the crash occurs: Xceed SmartUI Run-Time error '0'. The SmartUI become grayed out and is not more usable.
I will try to create a simple project, if I can. But I cannot post the whole project which is way bigger :-)
