You are absolutely right - I try usually to avoid such things by better
design / coding...
The problem occurs usually with third party components / OLE Automation
Servers I have to use...
They do whatever they do ok but sometime throw OS exceptions - I need to
catch these...
Otherwise my whole app behaves strange ( if I don't catch them )...

Even when using __except etc. with some exceptions it seems impossible to
catch them - esp. when they occur inside OLE Automation servers I use...
And this really makes my app reacting really strange when this happens...

Is there any way making sure that really all exceptions get caught ?
