It would seem the position aware timer (which is nice, by the way, epecially since it is integrated right into version 1.19.00.10) does not function as expected. When using Control-left arrow or Control-right arrow or clicking a pattern number, the time changes; however, it does not when using the Go to... dialog.
Steps to reproduce the bug:
1. Create or open a module with two or more patterns in it.
2. Use either Control-left arrow or Control-right arrow and note the time change.
3. Use the Go to... dialog and go to a different pattern. You should observe that the time does not change.
Has it occurred in previous versions? Yes
Which one(s)? 1.19.00.00
