This morning I updated to the latest and greatest version of MBS. Now I get the above mentioned exception:

`2019-01-30, 13:04:29 Buffer:
2019-01-30, 13:04:29 --------------------------
2019-01-30, 13:04:29 An error happened:

2019-01-30, 13:04:29 Type of Error: UnsupportedFormatException
2019-01-30, 13:04:29 --------------------------
2019-01-30, 13:04:29 Stack:
2019-01-30, 13:04:29 
Sub Application._CallFunctionWithExceptionHandling()

2019-01-30, 13:04:29 ErrorReportWindow.Constructor
2019-01-30, 13:04:35 ErrorReportWindow.Constructor done`

Of course, I can just ignore the exception. But why do I get it? Code is simple:

[code]'make nice mouse cursor to show that we are over a link

if elementInformation = Nil then Return False  
if elementInformation.HasKey(“WebElementLinkURL”) then  
app.MouseCursor = System.Cursors.FingerPointer  
else  
app.MouseCursor = System.Cursors.StandardPointer  
end if  
Return True[/code]

No error message with UnsupportedFormatException?  
I don’t have many UnsupportedFormatException raised in my plugin code.

And do you know which line it is?

The debugger sort of goes into limbo. As soon as the MouseOver happens Xojo becomes active but doesn’t drop into the debugger. So I can’t see anything. I added an “#if debugbuild then return” and the exception still happens.
