cattr.width = 160 / numColumns;
}
table->numColumns = numColumns;
if (table->currentColumn >= numColumns)
table->currentColumn = numColumns-1;
InitTable(table);
}
InitTable() does things like setting item styles, custom draw routines,
enabling rows & columns, etc. originalAttributes and savedOriginal are
globals of the proper types, and they are cleaned up when the form closes.
First time this routine is reached, everything works fine. Second attempt
goes berserk. I've seen font, menu, and bus errors (all in POSE), which
suggests I'm corrupting something or accessing things I shouldn't.
Suggestions?
