Periodically I get the following exception

System.NullReferenceException: Object reference not set to an instance of an object.
   at MicroFour.StrataFrame.Messaging.MessageForm.ShowMessage(String MessageText)
   at SFB.Alarm64.Alarm64_CustomerMF.EditInstallation()

I use Messageform a lot, as it's a lot more aesthetically pleasant than Messagebox. This isn't specific to 1.6.7 as I have experienced it quite a bit over the last few versions.

Is there anyone else getting this at all?

thanks
