Summary: Windows : exception in orexxole.dll when omitting parameters

Initial Comment:
Using the debug version of ooRexx 4.0 compiled with Visual C++ 2008 Express Edition, I have an exception raised in orexxole.dll when running this code :

excel = .OleObject~new('Excel.Application')
excel~visible = .true
workbook = excel~workbooks~open(directory()"\datas.xls",, /*readonly*/.true)
workbook~close
excel~close

The problem comes from the omitted parameter in the call of the method "open".
The patch fixes this problem, but I don't know why the try/catch in IsInstanceOf did not catch the exception... 
I did not test with the release build. Maybe is it a problem only with my configuration ?
