When I use the calendar in 4.30 it shows up as "Page not found".
I reproduced it by:
1. opening the "Accounts (31)" example app.
2. change the date from mm/dd/yyyy to the correct <g> dd/mm/yyyy format.
3. generate, compile, run
4. click on invoices
5. click on insert
6. click on "Calendar" button (this works)
7. select date, and window closes.
8. click on "Calendar" button again - THIS DOES NOT WORK.
On my apps, the first invocation fails, but in the example the 1st invocation seems to work. Weird!.
