When trying to add a new server, I get this crash:

145         return txtDescription->GetValue();

And the backtrace:

(gdb) bt
#0 0x00076914 in frmConnect::GetDescription() (this=0xbfffea10) at ui/frmConnect.cpp:145 #1 0x0003db88 in pgServer::Connect(wxFrame*, bool) (this=0xf44a1b0, form=0xb853600, lockFields=false) at schema/pgServer.cpp:108

Hm, seems the txtDescription isn't valid; why? When reviewing the code in frmConnect, I wonder about those Destroy() in OnOk() and OnCancel(); looks dubious. I'll check this later.

Also, attached is the way the add server dialog looks on the Mac. There seems to be some kind of size issue.

This is probably our well-known font inheritance problem. Pplease verify this by adding SetFont(parent->GetFont()) in src/mac/control.cpp line 397 (after SetSize....)
