[DUG] EAccessViolation on StdWndProc

[Leigh Wanstead]

Hi Myles,

That is all the information related to stack I got. How can I code to catch
the error even considering modify classes.pas?

TIA

Regards
Leigh

No they are not the same.
Madexcept is very good and to be recommended. IMO the best of these kind
of products.

That stack trace does not look complete or correct - but hard to tell,
just looking at it - it feels wrong/incomplete.
