[Mono-list] A couple of SWF questions

[Paul F. Johnson]

Hi,

The code attached works fine with Mono. VC# moans like crazy and I'm not
sure why - comments would be welcome.

The code also has 2 problems. The first is that then Address label
doesn't appear and it should (could someone confirm this so that I can
file it in Bugzilla) and the second is the KeyPress event for the
NumberBox is being ignored (from what I can see). Again, if someone can
confirm this, I'd appreciate it.

The code compiles without a hitch under Mono 1.1.13. I'm using the
Fedora Core RPMs over the build from source (don't ask).

Sorry about the length...
